( Also Piston should be Measured with outside Micrometer and Cylinder should be measured Top middle and bottom with a inside micrometer to determine clearance's then Ring gap can be figured.

Ya, I know what the stock ring gaps are. Last time I had mine set I went with what Manley tells you to do and added a coouple, and in my opinion is too tight.
For a .020 over engine running their pistons/rings they want you to be like 0.018 on the top and 0.011 on the bottom.
