Originally posted by westcoaststyle I have a 3 angle on my valves. Couldn't tell you if it made a difference cause I did it all when I did my build. Supposed to be much better for valve seal though.
Agreed. A blown application like yours is one of the few where I would definitely consider a 3-grind, and in this case, it's nothing to do with flow around the valves, but because it should create a better seal if the seats are properly ground too. Even or someone running 11lbs of boost like you, I still say 5-angle is way overkill. May as well throw your money away. Or give it to meeeee.
