SS/AH Head rules

Spyphish · 09-18-2012, 10:30 PM

I am new to class racing and was recently DQed at Indy trying to run the Hemi Shootout. It really did not matter as I was not fast. I do have 4 1/4"-20 allen bolts visable on the outside of the head as a valvetrain saftey measure and my NHRA letter cited "No external modifications to the head". So I am removing them and acknowledge my mistake as they are visable. NHRA will allow me to pass tech at next race and all is well.

I now have a better idea. My question before I do it, is can I mill the intake runner past the top of the valve cover bolt holes, and use the bottom remaining threads to hold an adapter plate so I can put the valve cover back on so it will seal? This will allow me to open the intake runner up. Of couse I will have to hike up the intake as well. Will these spacers be perceived as an "external modification" since it seems I am already the "bad boy" of Hemi. I just hate to do all this work and not pass. Thanks in advance for your advise.

I'd suggest a long talk with your Division Tech Director.

apparantly that was legal as of indy. If it continues to be, than I will be back out after I get a new engine done, and watch me turn a tenth into 2 tenths.

I do love the way you think Charlie, reminds me of The Babe pointing to the out field as to where the ball was going over the fence. Keep up the good work.
