Don't open the bowl as wide as the seat!! it should be only about 75% of the valve size.

I open up the bowl 15 years a go. well past that!

With the 2.02 cut in, there is vary little bowl cut from the 75* stone. Just something i will have to live with, with these heads.The bowl area is over 2" right now!:read2: :angry7:
