Loading... Please wait...These 1.900" SBF intake valves are available for select SB Ford heads such as the Gt40 and GT40P heads. Both of these heads come with 1.841" intake valves so the first oversize would be 1.900"
Oversize valves are typically used to increase flow by machining the heads to accept larger valves followed by blending the pockets w/ a rotary burr at the same time.
Consult your machinist for the costs involved to fit oversize valves to your castings.
