We all know that a good cylinder head can make a big difference in power on just about any engine, but what about AFR heads in particular? They are known for being one of the finest cylinder heads out there and in this video Richard is going to test multiple sets, on multiple small block Fords, to see just how much power they are worth. How about 100 horsepower? Is that possible with just a head swap?
Video Description:
WHAT ARE THE BEST SMALL BLOCK FORD HEADS? HOW MUCH POWER ARE AFR 165 HEADS WORTH ON A 5.0L FORD? HOW MUCH POWER ARE AFR 185 HEADS WORTH ON A 331 FORD? CAN I GAIN 100 HP WITH A CYLINDER HEAD UPGRADE? WHY DID MY HEAD UPGRADE ONLY ADD 15-20 HP? HOW GOOD ARE AFR FORD HEADS? WHEN I ADD CYLINDER HEADS, DO I ALSO NEED A CAM AND INTAKE? WHAT INTAKE SHOULD I RUN WITH PORTED FORD HEADS? WHAT IS THE BEST 5.0L CAM? CHECK OUT THIS VIDEO WHERE I RAN TWO HEAD TESTS ON SBF MOTORS. TEST NUMBER 1 WAS THE ADDITION OF AFR 165 HEADS ON A STOCK 5.0L MOTOR, TEST NUMBER 2 WAS THE ADDITIONAL OF AFR 185 HEADS ON A MODIFIED 331 STROKER. THE GAINS WERE DRAMATICALLY DIFFERENT AND HERE IS WHY!
