I have a set of dart pro 1 alumnum sbc heads.The intake ports are just slightly taller than the ports on my edlebrock perf RPM intake. I have already port matched the special thicker fel pro gaskets to the heads. My question is..... Is it worth the time to port out my intake to match the heads? there is enough meterial on the intake to do it. And if so would there be any gains in hp. Also these heads hae 215cc intake runners. There going on a 388 stroker 64cc chambers. falt tops 2 eye brow. Comp cams .480 lift 230 [email protected] magnum cam. I intend to keep the rpm range around 6000 max. Are these heads too big for my engine? I bought them incase I wanted to up the power in the future but right now im just wanting a driver and occational drag race.
