Hi Jon,

That’s what I do too, plus crowd the margin ever so slightly towards the 'head' of the valve from the center of the face.

In many applications in fact, the valve face will be ground to a 45-degree cut and will land on a seating surface cut to 46 degrees. This 1 degree of "wedging" effect will actually help in the seal as well as kinda "lock" the valve down during it's time at rest to help the cooling.

If you’ll notice, a correctly and properly ground valve/seat assembly will feel almost as though the valve is lightly “stuck” to the seat without the springs and keepers in place.

How's things going up there in the great North anyway? :>)
