Professional Cylinder Head Porting

Horsepower Heads is far more than a traditional cylinder head porting company…

Our point of difference comes from fully understanding the purpose of your engine and the application in which you will be using it. We plan any modifications and part selections specifically to suit you.

This approach and 30 years dedicated to the craft are what gives each of our clients a cohesive engine combination and a winning edge.
