Competition Series

SI Valves

 

This model features an undercut stem in the head area. In addition to reducing the valve weight (which provides benefits in opening rate and RPM limits) the radius of the head is such that it significantly improves air/fuel flow. This model enjoys great success when used with stock heads, as well as modified versions. Fully swirl-polished Chromed stems and Stellite tips.

Ideal for tough racing applications of all kinds. Now available for imports.
