BILL MITCHELL PRODUCTS BMP Cylinder Head Aluminum Chevy Small Block VORTEC 215cc 23Degree 2.080″ x 1.600″

Bill Mitchell Products has taken the Chevrolet’s Vortec-style cylinder head design to the next level with these superior-performing 23° BMP SBC Aluminum Head with a huge 215cc intake runner. Originally known as the Motown from World Products, these Head combine high-flow ports with generous 2.080” diameter Manley stainless steel intake valves and you can see where the extra power comes from. 

They’re available bare, or in three 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.
