Hi, Here's the situation! I'm doin a rebuild on a 454ci, and its the early 454s and the heads are 118cc and I'm wandering if I should spend the xtra money and raise the compression to around 9:25.1 or so I think original is 8:5.1 or lower. If I did I would be getting HigherComp. hypereutectic pistons which means I would have to balance also! OR shave the heads and go with original cast and not balance but some guys say even an all original bigblock should be balanced? like they were never balanced real well!! Any help Appreciated!
