Compression

I believe the valve pockets are symmetrical and 6ccs. If it were me, I'd be taking the pistons down to be zero deck and run the Felpro .039 gasket. That should be around 11.2:1 with a quench of .040ish. With a cam around 255°@.050 you will be fine on pump 93. Also on the cam, I'd go another .030-.040" lift on that roller. The offset intake rocker loses some lift, plus you have to take out the lash figure.
