Input for SCR/DCR

What is the general consensus for compressed stock graphite head gasket?
Piston above the deck dimension?

If I use .057 for the gasket and -.007 for the Piston above the deck

head cc's for the LS1 = 67 - I get the advertised 10.1:1
head cc's for the LS6 = 65 - I get the advertised 10:5:1

any comments, I been trying to confirm any physical dimensions for the LSx and get different values depending on where you look!

TIA

The compressed stock GM head gasket is .052".

You also need your cc's of valve reliefs if you have any,cylinder bore and the bore of the head gasket.

I've seen that dimension, however it just doesn't compute when double checking the LS1/LS6 SCR.
