2009 NHRA Rules

Dave,

It may be what you think, but the average guy is thinking of valve jobs as valve jobs. Also, the paragraph regarding Superstock references both STOCK ANGLE, and the +/- 1 degree (my second paragraph - quote on page 114), so I believe you're interpretation is incorrect. Yes the valve angle/deck surface relationship will change with angle-milling and NHRA is aware of that, but then they wouldn't need to include "STOCK ANGLE" in that paragraph. It's still a contradiction.
