HOW MUCH ARE AFTER MARKET IRON & ALUMINUM HEADS WORTH ON A BBC? STOCK REC PORT VS SUMMIT VS AFR 290

Описание к видео HOW MUCH ARE AFTER MARKET IRON & ALUMINUM HEADS WORTH ON A BBC? STOCK REC PORT VS SUMMIT VS AFR 290

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?
