Power Heads - Performance Engineering



We have built literally thousands of CNC ported factory cast iron heads for over 10 years. POWERHEADS have been featured in many high performance magazine articles, and for good reason . . . THEY MAKE HORSEPOWER. Do not under estimate a good set of ported factory castings. POWERHEADS provide exceptional low end throttle response and great mid/top end power as well. If you want the original Ford castings and demand the finest workmanship, POWERHEADS will build you the best performing heads. . .
