Freedom Series heads have started a revolution
in the performance world. We have custom designed
a head to meet the needs of the SBF world, while
keeping the quality high and the price reasonable.
The SBF heads come as cast with a 185cc intake
runner, US made bronze guides, and our 5 angle
valve job. We have seen these heads add over
75 hp over a set of ported "E7" 5.0 heads. These
heads come standard with a 60cc chamber and
valve jobs for 2.02" / 1.60" valves
