Ideal for boosted applications would be 62cc-64cc heads, or so (depending on PSI). Bottom line, it should be fine right now for NA, and I'll switch the heads/lifters/injectors when going FI (even though the lifters are brand new, it's cheap insurance).

I come up with 10.33 with a .044 quench which is great. The engine should run strong. However, if you do go with a blower don't drop the compression by adding a thicker head gasket. A 64cc combustion chamber will drop the compression down to about 9.75 and would keep the .044 quench. That's a little high but with an intercooler or meth injection it won't be. Better yet would be a set of AFR's with 72cc combustion chambers which would give you 8.97:1.
