fit properly, are easier to install, and shaped to help air flow instead
of just copying the OEM design. The GSC Power-Division valve guides are
made from true C67410 Manganese Bronze and turned on a dedicated
precision CNC turning center. What this means for you and your installer
is less time fitting guides to the head due to holding the tightest
tolerances in the industry with the best quality control possible.
