The debate over iron vs aluminum heads has been a long argued one. For years, the old school guys would swear that iron was better for towing and this and that and heat retention and blah blah blah. And then the aluminum head guys talked about power and heat dissipation and blah blah blah. So does it really matter? And are low buck Summit BBC heads worth the money as an upgrade? Do you guys think this 496 test engine is going to love an AFR head more? It just might.
Lucky for you, Richard is going to test several different big block head options to show what it does on this engine right here.
Video Description:
HOW MUCH POWER ARE HEADS WORTH ON A BBC? SHOULD I UPGRADE THE CYLINDER HEADS ON MY BBC? HOW MUCH POWER CAN I MAKE WITH STOCK HEADS? ARE REC-PORT BBC HEADS ANY GOOD? SHOULD I RUN IRON OR ALUMINUM BBC HEADS? DOES SUMMIT MAKE GOOD BBC IRON HEADS? HOW MUCH POWER ARE AFR HEADS WORTH? CAN I MAKE MORE POWER WITH REC PORT OR OVAL PORT HEADS? CHECK OUT THIS VIDEO WHERE I RAN STOCK IRON REC-PORT BBC HEADS ON A HEALTHY 496 CHEVY. I THEN REPLACED THE STOCK HEADS WITH REC-PORT, IRON HEADS FROM SUMMIT RACING. AFTER TESTING THE IRON SUMMIT HEADS, I INSTALLED AFR 290 OVAL-PORT HEADS. CHECK OUT THE GAINS OFFERED BY THE HEADS SWAPS, BUT CAN THESE NUMBERS BE DUPLICATED BY PORTING STOCK HEADS?
