You can use a radiused cutter. That's not illegal.

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. ;-)

Re: U/SA 302 ffffford build
 

My Citation HO 2.8 came stock with 5 angles..That made tech nuts, for sure, at that time
;-)

Re: U/SA 302 ffffford build
 

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

Re: U/SA 302 ffffford build
 

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.

Re: U/SA 302 ffffford build
 

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

Re: U/SA 302 ffffford build
 

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?

Re: U/SA 302 ffffford build
 

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

Re: U/SA 302 ffffford build
 

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

Re: U/SA 302 ffffford build
 

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..
