Welcome to Pro-1 Racing Heads

Aprilia, BMW, BRP, Buell, Ducati, Harley-Davidson, Honda, Husqvarna, Kawasaki, KTM, Rotax, Suzuki, Polaris, and Yamaha

cylinder head rebuilding services. We are one of the country's largest power sports cylinder and head re-manufacturers. We specialize in CNC MACHINED valve seat profiles which enhance air-flow and extend valve seat life. Other services we perform include valve seat and valve guide replacement, along with cylinder head porting and flow-bench testing. Here at Pro-1 Racing Heads we custom craft our own valve seats and valve guides in-house, however, we also carry a full line of name brand cylinder head parts.

Try Our All-New Vapor Blast Cleaning Service!

The most recent addition to our service line is vapor blasting. Available as a standalone service, and also included with all of our head modifications, vapor blasting removes dirt and grease residue from your components, while leaving a much smoother and shinier finish than both soda and bead blasting.
