BILL MITCHELL PRODUCTS BMP Cylinder Heads Aluminum Ford Small Block 310cc 10Degree 2.250″ x 1.625″
The BMP engineering team has developed what is the ultimate competition cylinder head for 302/351 Ford small block applications. It features a highly advantageous 10° valve angle (with parallel rocker arm mounting) and some humongous ports. The “as-cast” intake runners are available in 275 and 285cc with huge 102cc exhaust ports. Add the CNC porting option and a 310cc intake runner is yours. Designed for use with all power-adders, the 10° BMP SBC comes with provisions to use two extra head bolts per cylinder as is offered with the companion BMP SBF Aluminum block or WORLD Iron Block.
- Heads utilize standard Windsor Bolt Pattern. Some modifications may be required when using standard Windsor intakes.
- Custom Sheet Metal or Edlebrock #2868. Some modifications are reqired to the intake face of the cylinder head to accept the Edlebrock bolt pattern.
- You must make sure that the intake water cross over ports line up with the holes on the head.
- For crossover water passage, you may have to drill two holes into the head to allow water flow between the intake and head.
- Use a gasket as a template locate your drill points.
