racing titanium retainers, chrome silicon springs, steel collars,
and keepers as required for one engine.

reduces valve float in the high revving engines, adding durabil-
ity and reliability to the engine.

VALVE GUIDES
We choose to use C63000 nickel bronze as a material
to make valve guides because of its ideal characteris-
tics for the application. The 4-5 percent nickel content
produces superior resistance to wear, and the approxi-
mately 80 percent copper content delivers outstanding
heat conductivity.
