Hey everbody. I'm having some motor mods done soon, and I was wondering what exactly a 3-angle valve job was. I've heard of it many times before, but not sure exactly what is done. Is it worth having done? Also, you who have had it done, what did you pay for it? (If you don't mind me asking.)

Thanks.

 

Basically they put three surfaces on the edge of the valves and on the head where the valve makes contact. It makes the valves seal a lot better, resulting in better engine compression. A definate must in engine building

 

so would a 5 and 7 angle valve job be the same, but higher performance? if no one minds me asking, how much does a 3 angle valve job cost?
