►BBC Alum. Heads



ALL BMP CYLINDER HEADS ARE PRICED INDIVIDUALLY

This highly evolved, race-proven cylinder head is capable of supporting in excess of 800 horsepower in “as cast” form. BMP BBC aluminum heads are available with 310cc or 350cc intake runners. The exhaust ports are 132cc. For those seeking more power, The BMP BBC Aluminum heads are available with CNC-ported 119cc combustion chambers and ports. This raises the bar to 345cc or 375cc intake runners. The port designs were developed have proven their effectiveness on the track and the street. The net result is a head that combines excellent flow and velocity and has been proven to produce 40 horsepower more than the as-cast BMP BBC on a 572 C.I.D. engine. It’s also a great value!

They’re available bare, or in four different assemblies that are designed to match your camshaft’s valve spring requirements. A multi-angle valve job and Manley stainless steel valves make the assemblies an excellent value and a real time-saver for engine builders. World Products has built over 10,000 Engines using our Dyno proven Cylinder heads. Over 10,000 Dyno pulls have given us the results you are looking for.
