STAINLESS STEEL VALVES
Made from the highest grade stainless steel, this
new Crower valve is a must for high horsepower,
high boost and high rpm applications. The exclu-
sive “Pro Flo” head design delivers a significant
increase in cylinder head flow figures, while the
tip area is hardened to RC50, including past the
critical keeper groove area for added strength.
Fully CNC machined and swirl polished to insure
that you will get the best performance valve
available on the market. Choose from standard
and 1mm oversize. Titanium valves also available.
Duration figures are taken at the lobe.
