Which cylinder heads should I run on my big block!?!? This is a question that has been asked by roughly a jillion people because not everyone is building a full-tilt race engine which means that not everyone needs giant rectangular port heads that flow a million cfm. So what are the right heads for a 468 build? That depends on what camshaft, what power you are looking for, etc, but this testing video has multiple sets of heads going up against each other on the same engine.

Video Description:

HOW MUCH POWER DOES A PEANUT PORT BBC HEAD MAKE? HOW MUCH MORE POWER DOES A REC-PORT BBC HEAD MAKE? CAN PORTED OVAL PORT HEADS MAKE MORE THAN STOCK REC PORT HEADS? HOW MUCH BETTER ARE AFTERMARKET BBC HEADS? DO THE AFR 265 BBC HEADS WORK WELL? HOW MUCH POWER CAN AFR HEADS MAKE? CAN THE SMALL AFR 265 (OVAL-PORT) BBC HEADS MAKE MORE POWER THAN THE BIG REC PORT HEADS? CHECK OUT THIS TEST WHERE I RAN A SET OF PEANUT PORT HEADS, A SET OF REC-PORT HEADS AND A SET OF PORTED OVAL-PORT (049) HEADS ON THE SAME 468 TEST MOTOR. I ALSO RAN A SET OF AFR 265 BBC HEADS. CHECK OUT HOW THEY ALL PERFORMED!
