What angle are you referring to ?

Glenn, I am referring to the angle that is built into the valve.

Always fun to go into a teardown with a Pontiac and watch them pick up the 45 deg. angle gauge and place it on your intake valve. ;-)

Quite confusing but I believe it's any valve angle allowed.

Glenn, I'm thinking the same way that you are (I guess that I can throw away a set of Aardvark heads). The online rules specifically says "VALVES must retain original valve angle +/- 1*. It does however say ANY valve job is legal which I will Assume (NHRA likes to keep us Assuming) goes to seat angles.

I think that I'll start a thread in the tech section. This needs to be discussed.

JMO the valve angle +or- they're talking about is the angle of the valve guide and any valve job means any valve job. Brian Seaberg 627

Here's a new interpretation, but I don't think so, Brian.
First of all, how would they check the guide angle?
Have you ever been through a tear down where they actually gauge the valve head sealing angle built into the valve? I have been..Many times, and that used to be what that phrase meant.
Today? Who knows?

Well Ive been through teardown 3x at Indy and pulled valves if that means anything..
