Description

The GSC Power Division exhaust valve guides are precision-turned components made from a proprietary Manganese Bronze blend. Designed with performance and aftermarket installation in mind, they feature extremely tight tolerances on through-hole concentricity to the outside diameter. This minimizes honing time for the installer and reduces the need for honing guide bosses on cylinder heads.
