Frankestein Racing Heads

Has anyone heard of them? I see they are doing some stuff with RHS cylinder heads but all they have are overall flow numbers and nothing matched up with a cam to show how well the head performs through the whole RPM.

Any experience or hearsay about them?

Thanks,
Jeff

do you think they should put down the Pro Stock heads they are working on to dyno 10 different cams in a LS motor?

Nope, buddy of mine just read a post that was made on YB about some things they have done with the LS7 RHS head. Some crazy flow numbers but you know how flow numbers don't always equate to great performance through the overall rpm.

As of right now, there hasn't been much proven better than the Mast without spending $5-8k on ALL PRO's.

Just curious if they (frankenstein) have done such great work, why I haven't seen or heard about them til now? It could be as simple as this RHS head is their first step into the LSX world, that is why I'm trying to learn as much as I can about the companies who are working on "aftermarket castings".

A monkey with a dremel can hog out an intake runner to get a large number.

Not sure what your deal is, I'm not a professional head porter nor do I play one in the movies, but I have been around long enough to know that just a High flow number means squat on a street car.

The intent of my post was to get some feedback from the vast array of knowledge on this board that spreads across all of the makes, models and types of engines. Someone "may" have heard about Frankenstein racing heads here and have some feedback that may be useful for me.

The RHS LS7 Big Bore head is actually made by DART Machinery, do you have anything to add about these?

[Pesce Nero]

if you simply look at the pictures you just might notice they weren't done by a monkey with a Dremel and I can probably rattle off 10 of the top head porters in the country that you never heard of.

if you want dyno charts comparing cams with there stage 1,2,3 or whatever porting then go to a shop that specializes in that one perticular service

Yes, I "can" tell the polishing has a lot of time put in to it, no doubt. However, when a company has flow numbers that are about 20-30 cfm higher at every .100 lift increment up to 1.00" of flow then something is either amiss, or they have found some magic; and I'm talking about world class cylinder head shops. I'm sure even "you" would agree with that "perticular" view. That is why I asked here on my home board where we have experience in new school, old school, chevy, ford, mopar etc. etc.

I'm going to put this into perspective for you.

If you did a set of heads for me and then I said "Hey, I found a shop that is getting 30 more cfm across the board than you did on my heads!" What is going to be your first response? I'm gonna guess; it would be something like"what is their aspect ratio, where are they making power, is it only peak power or across and under the torque curve, OR what are their port velocities?

I think you need to reread what you wrote in your first post. I understand what your getting at now but it took 8 posts and a couple insults to get there

things as simple as changing seat angles can make dramatic improvements in flow although none of them seem to last as long as the 45-46* angle that works so well for general purpose. And maybe they are just full of shit

The Frankestein guys say that they flow their cylinder heads on a SF-600 flow bench and they "don't" use a pipe on the exhaust.

Would this inflate flow numbers in any way?

Rays has the pacman flow pro model. It's the most badass thing I've seen someone put together honestly. It's wild.

My intent was not to insult by any means. Your original post struck me as "why would they waste time testing/backing up their work, they don't have time for that". That just rubbed me wrong as in "if you're not Pro Stock, who cares?" If that was not your intent, I apologize :cheers

If that was your intent, well then................:finger:

But, most Pro shops that cater to the street/strip crowd do provide real world tests like that in most cases because most of those shops get their bread and butter from that crowd.

can you post the flow numbers? I don't know where your seeing these numbers at

There is a point where they say the 600 becomes unusable. maybe around 380-400 cfm then you would need to use the 1200 although SF has come out with a 750 model now.

another thing is the SF-600 flows at 25" of water depression and you need to mathematically calculate it to 28" unless they use a flocom which is basically what I use that does all the math for the user

a pro shop will understand what you want to do. I'm not a pro but I try to think about every possible senerio when I'm doing a set of heads and usually discuss it with the person I'm doing them for. I would think if you told them what you wanted them for a street car, they would say, oh, you cant run our head that flows 450 at 900 lift on that

on another note, if they only have a SF-600, then they are not doing heads for Pro Stock

[Pesce Nero]

first off, I have been to LS Fest twice and have seen many heads that claim to go over 400 cfm so I dont think any of those posted numbers are out of line.

next thing is the Mast heads were only a 20hp improvement over stock heads. also, they take out all the titaniun and replace it with stainless steel, why?

another thing, an LS7 has all these super light parts inside of the motor but to really make HP you need to raise the RPM or stroke the motor, so bigger cam and shorter runner intake or go big and keep the RPMs down.

I really dont know how much HP your looking for or expecting

[Pesce Nero]

I just read the Mast heads are a different casting. and that cam sounds fimilar, like maybe the same one in the ls7 for sale on this board.

IDK, I wouldn't pay that kind of money for 20hp

Right now I make 580RWHP with stock heads, .660/.649 lift 246/252 duration on a 111 with a FAST 102mm throttle body and intake.

My goal is around 620RWHP, using the Mast Cylinder heads, bumping compression and including Meth into the equation. That shouldn't be too hard I would think being that Mast made right at 700FWHP in that article with a similar cam to what I will be removing AND through a stock throttle body and stock intake. Ed Curtis at Flow Tech Induction is working on spec'ing a Cam for me based on my goals and use of the vehicle.

That extra 40+rwhp could be easily attainable or it could be an oasis.........

for 4k, I would stroke it and you would have a monster.

how are you going to bump compression?

[FRDnemesis]

Most shops are milling the head to bump it a .5 point along with a cam grind that changes the valve event timing to raise that cylinder pressure. This is honestly out of my realm of expertise. I in no way am well versed in Dynamic compression vs. static compression. All I know is that is how most shops are doing it to bump it up.

The factory stroke is already 4.00, not sure there is room for a 4.100.

[Pesce Nero]

all I can tell you is that I probably had 75 hp pulled out of my car during Drag Week and I couldn't tell the difference.

As with their base cylinder head, you get the lightweight hollow stem, stainless valves.

Now they actually offer the Titanium Intake valve as an option; it is not listed on their website yet. But you can add over $1,400 to the price by checking that Titanium intake valve and Inconnel exhaust valve box and turn a $3,500 set of heads into a set that will push the $5,000 barrier. That cost is just not an option in my wallet.

The factory heads have titanium intake and sodium filled exhaust valves.


I'm gonna sell my current Heads/Cam/Spring Combo for $1,500 to help offset the cost.

[1998ta__1991rs]

why dont you try shaving your heads to get the extra compression and see where you're at

[FRDnemesis]

I'd hate to put $1,800 in my heads (aggressive port work/mill deck/replace exhaust valves to stainless and tumble polish my stock intakes, replace guides etc) and be "not as good" or "Just as good" with no room for growth. At least the Mast head is that good out of the box so to speak.

I don't know, I've tossed it around for a couple months now and every cylinder head shop I've spoken to and about every builder who posts about cylinder heads on LS1tech or corvetteforum has nothing but exemplary things to say about the Mast cylinder heads. Lots of shops use them in their own builds too.

This is one of those deals when it comes to a purchase of this size, I get a bit worried about making the best possible decision "the 1st time" and not having to learn from an expensive mistake.

If I decide to have my factory heads re-worked, my choices are (that have experience with this head) Darin Morgan at Reher-Morrison ($2,600) work them, West Coast Cylinder Head ($1,800) OR everyone's favorite Advanced Induction ($????).

I spoke to Ray a while back about doing my factory LS7 heads and would have no problem with him doing them if I was going to keep the car. Why not consider him as an option Jeff?

I'd just have the stock heads reworked. Ive seen a handful of them make 600+ rwhp without an aftermarket head.

[RoadconeTuning]

just pull the stock heads off have them milled .060, slap some JB Weld on top of the pistons and change the cam... boom extra compression and MOAR choppity choppity chop
