First, the advertised volumes are almost never right, the real volume of an unmolested head tends to be a bit more.do i guess right to think a 119cc head would raise the compression on my 454 BBC. currently i run 148 heads with 122cc but i have pretty tall dome piston. given i use the same gasket for both heads.
Mortec has the following info on the c/n 148 BBC head:so is it safe to say that if the 049 and my 148 were cc close and both had 2.19 vavles they would produce close to the same power. thank for the response guys.
