valve job???

What most people do not realize is, nearly every single modern automotive engine from about the 1940s all the way through now has at least a 3 angle job on the seat.

That said, the shop I use gets 150 for a standard 3 angle competition valve job with 3 angles on the seat and valve cut on a serdi machine. Never have asked about a 5 angle as I don't think it makes a noteworthy difference.
