I know you guys have way more real world experience then normal internet people so I want some opinions and suggestions. The square 4.125x4.125 setup is the ultimate for a road race setup. Aiming for 11.5:1 or so compression; I like RPM so even tho it is a torque monster I would like to be able to get at least 7,500 out of it.

Planned parts

New LS7 block
RHS Pro Elite LS7 heads (69cc)
Scat 4.125 Stroke Crank (Opinions and suggestions? Motor will always be N/A so can I go light weight?
Scat 4340 H-beam 6.125 rods
Wiseco -2.8cc Pistons
LS7 head gasket
Lunati High RPM Lifters
ARP Head Bolts (Studs are a PITA with the GTO brake booster)
Fast 102
Nick Williams 102
Ported LSA Oil Pump

I need opinions on Valves and Springs.
Will stock rockers with trunion upgrade work? They are light weight and don't seem to fail like the roller rockers do.
How much injector will I need?
I currently am running a comp cams double roller. I have cam signal issues during startup sometime so I need another option.

Cam would be spec'ed by the builder; I trust him.

4l65e would prob turn into a face plated t56 or maybe a PPG converted 1-4 t56 dogbox.

There's a couple LS7 441's for sale right now on the vette forum, for a deal!!!
