benefits of a three angle valve job?

i would say so, i think a good valve job is something like 10-15 horses. Also it affects duration a small amount.

i am getting a 3 angle on my e7s once i get done porting them....

i thought it was just to refresh the seal of the valve and restore it to the stock performance

3 or 5 angle vob job is done to increase the flow. It allows it's transition to be smoother which allows it to produce more power. It's worth it with or without Funny gas. just my .02

cutting more angles in the valve and the seat, makes it a smoother turn. If you look at the stock seat, its just flat. a 3 angle will make the seat and valve have 3 angles i believe, a 5 angle, makes 5 angles which is better flow.

more air = more fuel = more hp blahblah
