Thinking about putting aluminum heads on my 86. Stock block. I have switched to mass air. Anyone know if I can get away with not dyno tuning after the heads install? Will I be leaving a lot on the table if I don't get it tuned? Anybody do a heads and mild cam swap and not alter the tuning. I imagine I'll need to step up to a 195 fuel pump and 24 pound injectors. Looking for input. Thanks
