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..

And then? Did they check the sealing face angle of the valve...any one of those three times

Mark, no disrespect intended, please read the rulebook, it says any valve job allowed so they don't check valve angles that I know of..my apologies for taking over this thead, I'd much rather talk about the 79 mustang build..
