Could anyone give me the dimensions for inlet and exhaust seats for a non skull triple head.

Hi Dave - Always best to remove old seats first - then measure the absolutely round hole, I used seats that can be machined - so each one fits each individual hole with the right interferance fit. - Regards - Phil

same as Phil, we remove the seat and then skim the pocket to make certain hole is round
then we custom machine a Tungsten Carbide seat to size
fit it using liquid nitrogen

What interference fit are you using for the seat?

Depends on what spec material the seat is made from - also if head is plain aluminium or cast skull - best to get initial guidance from seat manufacturer - Regards - Phil
