were all right they just don't know what they want us to do

Bob Shaw is right; wait a little bit before jumping onto the "any valve job" wagon. The word on the street is that clarification will happen before Christmas.

I just wonder how many guys out in Drag Race land are in the same boat I'm in... Last fall I spent a weekend doing a flog on my flow bench & head machine. You know the drill.. spent about 40 hours in one week end. I was working on valve angles for a, then, legal valve job. On Monday morning I ordered 2 cutters from Sunnen for my VGS 20 machine with the latest greatest angles on them. That totaled almost $200. If I had known about the new rule I could have worked on something that was productive instead of just practicing all weekend & helping Sunnen's bottom line on Monday. I'm a little pissed about this latest enhancement of the rules. Not the change, the way it was kept in Glendora, Or those outside The ivory towers didn't mention it. As time passes I think there will be more & more changes, like any big business, as people try to justify their positions. I'm just about ready for a period of 5 years racing without any changes in any rules.
I'm not going to hold my breath on that one.

# 1 DON'T KILL ME! but....this is my take on it.......we..as in stock racers BITCH & want rules inforced! That being said with this rule change it make it easier to "inforce"! you have one angle to check & if it's good......"your good" !

If they didn't allow superceded parts or change 'little' rules here and there, cars would've (or should have) hit a performance wall years ago, and guys would have lost interest. If it weren't for the changes over the years, you think they might've had the horsepower rating figured out for a late '60s smallblock by now? LOL

I agree with Greg, valve angle and valve seat angle are two different items. So, I am interpreting any valve job as a multiple angle cut on the seat not just a 3 angle cut.
