CHEVROLET APPLICATIONS
Claimer Series (V8)

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 is significantly improves air/fuel flow. This model enjoys great success when used with stock heads, as well as modified versions. Many available with Black Knight coating. Fully swirl polished. Chromed stems and Stellite tips.

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