With the head on the block with NO gasket. .600" valve lift .086" valve to wall, .700" valve lift .082" valve to wall. I used my numbered drill bit set to measure, these numbers aren't exact I'm sure but it gives you a good idea.
Ok, thanks man. Looks like it's very close if i go with 2.14"iv heads. ~.04",hmmmm, it's not much, but it's enough.:)
That low CR (11:0), is what i'm thinking next, is it too low, or how that shortblock work with those heads? When i purchase that x-block i was sure that i can go at least 4.08" pistons but no, not this time. But maybe i have to try how these massive heads works on "small" bottom engine???
