Re: stock head jobs
It is my understanding the information on the NHRA website is a partial list and reference to the 2008 rulebook is required for complete details.

Re: stock head jobs
Read at the top of the head section , you still must maintain the stock valve angle. .... The .250" cut depth looks like it can be measured from the bottom of the seat now , instead of the top as in the past. ..... Tom
