I am running a set of the ol fuelie camel hump heads on my stroker 383. the heads have had a lot of work done.2.02 / 1.60 valves,larger springs,ported,polished etc. I am considering changing to an aluminum performance head due to adding a 671 supercharger. Does anyone have any input on weather to keep these heads around or should i just part with them? Any ideas what to ask for these. Right now they are on the motor and it dyno'ed at 613hp so I know they work well.
