Rusty, I am looking at a similar build on a 1977 318. I was looking at the KB167s. The stock pistons before dissassembly are about .100" in the hole at TDC. Arent the KBs a bit taller, closer to a zero deck height? The block will need to be surfaced "decked" anyways. The heads I have are rockauto reconditioned 302s. I have not CCd them yet to verify. Going to borrow a burette from a buddy of mine to get a number. I am ready to pull the trigger on a set of KBs but dont want to if they wont help get the compression up there.
