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
21-4N EV8 stainless steel.
