Quick question, the heads that came with the engine have been completely gone through to include new valves, spring, seats, rockers(stock cast), keepers, etc. now I need to make a decision. Do I bolt these on as is and live with the fact that it’s a 1975 351w. Or do I remove the air injector bump by porting them out at a minimum hopefully helping them breathe better. Or save up and go aftermarket heads and try and sell these.
