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. Valve faces are re-ground in centerless valve grinding equipment and the tips are ground to remove pitting from tappets. 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.

Performance upgrades are also available including porting and custom valves in both standard and oversize.
