New engine issues

Btw..... the math doesn’t add up here.....

318+.030, zero deck, pistons with no dish or valve pockets, std composition gasket...... the heads would have to be about 73cc’s for that to only be “9:1”.

Did anyone cc a head?
What casting number are they?

Did you verify that the pushrods you swapped in were the same length as what you took out?
