The 4P Billet CNC Race Head is the ultimate for those wanting to push the limits of cylinder pressure and horsepower levels.  If you are wanting to push power approaching or exceeding 2000hp, this is something you need to consider for its strength and rigidity.

We offer this head DRY and with water passages.  Please consider that you may want to run this completely dry in an alcohol engine at power levels listed above or with very high levels of nitromethane.  Our preference is a wet block with this head dry.  It is easy to tune and the wet block will help you to manage piston growth with heat.  Some guys choose to run both completely dry.

Our machining is absolute art, and these are proven pieces that have raced many times.
