Woah - I wonder now after reading this thread if my newly-built /6 has too much compression. I decked the block 0.050", and the heads 0.030", aiming for about 9.5:1 compression. Pistons are +0.030", too.
I'm in the process of putting my slant together and with 90 thou off the block, 10 thou off the head with my flat top pistons also 30 over, several sites estimated i would have about 9.4 to one with a composite head gasket and about 9.7 to one with a stock steel head gasket and DCR of about 8.1 or 8.3 depending again on the head gasket used. I would estimate yours ought to be less than 9.5 depending how far down in the hole the pistons are. Maybe the block and/or head has been previously cut?
