We offer a full range of services for these heads. From O.E. blueprinting to fully ported heads for racing. We also offer conversions to 8mm valve stems to greatly reduce valve weight, enhancing valve-train stability.

We have developed over the years a variety of casting repair techniques, fixtures and custom tooling as well.  If you have any questions about the services we offer please feel free to contact us.
