GUIDES- Valve guides are manufactured here in house out of nickel bronze C63000 alloy (Ampco45) which provides superior wear resistance and heat conductivity.

SEATS- Valve seats are cut using carbide cutters in Serdi equipment. This provides a precision multi-angle valve job which far exceeds the performance of the factory seat profiles. Final vacuum testing ensures a quality valve job.

ASSEMBLY- All parts are carefully cleaned and inspected. Only serviceable parts will be re-used. Heads are re-assembled with new quality viton seals and assembly lube. Deck surfaces are checked for flatness and dressed.

Porting is also available.
