Going to have a new valve job done on my heads and I think a read somewhere on the board that buick stage 1 heads like specific angles cut on a 3 angle valve job. Im looking for any help whome has experimented with this. Chris
A good standard is 30 degree top cut, 45 degree seat, 60 degree below that and 70 to 75 below that. A 30 dgree back cut on the valve also is good. Jim Burek
