134F Exhaust Valve Late Style NOS Stellite Faced (S303)
This is an NOS military surplus valve. This is the late style exhaust valve for the 134F engines. This is the style used with the roto-caps. This is a very high quality exhaust valve and is Stellite faced to work with the new fuels. Please look closely at the base of the valve because there is a big difference between the old style and new style exhaust valves and they way they are held in place.
