Brodix Head Hunter/HHMC

Cylinder head and manifold specifications are not available for all of the products we offer. If you can’t find information here for your particular cylinder head or manifold, be sure to give us a call because Frankenstein Racing Heads works with all makes and models of cylinder heads and can design a package to make sure you get the most out of your motor. We specialize in finding power where others simply can’t.

We also don’t race flow benches here at FRH. The harsh reality is that flow bench numbers may sell heads, but they don’t necessarily make power. They are a good tool to aid in the design of a port but far from the end-all-be-all in determining the potential of your engine. 28in-Hg at room temperature simply cannot compare to the 1000+ degrees and massive pressures trying to get out of a running engine. And there is no simulation for dynamic compression. Because of these facts, we prefer to rely on dyno testing, and more importantly, real world testing at the racetrack to develop all of our cylinder head designs. The net result of our experience, engineering backgrounds, and real world testing is a superior cylinder head that will put you in the winner’s circle!

So next time you find yourself caught up in a sales pitch about flow bench numbers, remember, when’s the last time you saw one of these at your local track…
