Twin Cam Cyl Head Service

Pro Twin Performance cylinder heads offer high performance with exceptional drivability and dependability. Throughout the entire reconditioning process, great care is taken to ensure perfect valve train geometry. Finished heads will have combustion chamber volumes calculated and machined to yield the desired compression ratios. Special order heads can be set up to accommodate different pistons. Otherwise, these are the same heads included in our Custom Performance Packages.

*When you check out, please include build information. Pro Twin Performance Cylinder Heads are built to your specifications so you must know your piston dome volume and desired compression ratio before we can build them for you.*
