Stock 318 building with Justin
Got the heads back.
Cc'd the chambers @72cc...that coupled with pistons .057 in the hole...8.1 compression.
So...Gonna mill'em about .047 to roughly 63cc
Taking .040 off the face as well for fitment, it's a little light the formula.. but intake gaskets come .030-.060 and then some so it will line up fine.

[email protected] ootb..is probably around .047 crushed/typically...so using that figure and 63cc head, if the Schneider 256/260 hyd is used its actual ivc of 58...probably adv it 2 degrees piston would be .057 in the hole... do the math and it looks something like 145 psi cranking..Something like 8.78 static. 7.4 dynamic. Stock'ish.
