Copper Valve Seat 1.550 x 1.200 x .250

Description

Beryllium free copper valve seat is to be used with titanium valves.  We recommend .006 of press fit in cast alum cylinder heads. The valve seat has the press tolerance machined in to it. If the builder machines the head to 1.550 you will have .006 of press. The ID of the seat has been made a little smaller allowing the builder to cut the center out to fit the valve size they need.
