Back to the machine shop...

To the OP:
What is the quench dome height of the piston, and what is your current deck clearance for the other part of the piston?

What is the quench pad area depth set to on the heads?

If I bolt it together with a .022" compressed steel shim head gasket I will have .062" between the quench dome and the head, that is more than I want. Again, with my cam I will have an issue controlling detonation at .062" (coming from Big Block experience). I am rethinking which way to go, might be cheaper and easier to take .030" off the heads instead. That way the radius that the open chamber has as it curves to the head deck will be reduced, making the quench block fit in the head with less dead space around it, making it more efficient.
Glad (for the most part) I posted this. I love the exchange of ideas!
