So I am grinding my valves and I cant really find any specs online. I need to know the valve face angle, and the valve seat angles for the intake and exhaust valves on a Trick Flow Twisted Wedge Track Heat (the new street/stip heads I believe are the same thing) head. The intake valves are 2.02" and the exhaust valves are 1.60". Any help would be great thanks.

IIRC it's 37-45-52 on the seat and 45 on the valve. Do the 45 degree primary on the valve and then a 30 degree back cut. Sometimes you can improve flow by changing the backcut angles just a little but but that would depend on the head and you would need a flow bench

If you have the head in front of you and you can't figure out the valve angle you might want to reconsider this move.
