Pro Valve Seats are made of premium hi-chrome, stainless steel material for extra long life in performance engines. These seats are triple the strength of factory cast iron seats and will hold up to all types of fuels. When it comes to dependability, these small details are part of the secret of why our engines last so long! 40mm Exhaust valve seats are designed for use with our 40mm exhaust valves, see Part #: 1023036.
