Small block Chevy Cylinder Head questions

Lew,
There are quite a few excellent guys out there who do very good work. You can do a perfect valve job on a set of heads for Stock and they can still run like crap, if it isn't the valve job those heads need. With Stock and Super Stock, it is not just doing quality work, but also having years of experience so that you know exactly what work to do. You can do an extremely good quality 3 or 5 angle valve job, but if the angles are wrong and/or you use the wrong valve, it won't run on a Stock engine. Only experience teaches you what a particular set of heads wants, and how good they have to flow to run.

I only have a 2007 nhra rulebook which clearly states "Pushrod guideplates permitted only when item was OEM for engine used" can anyone clarify this Thanx Trevor

NHRA 2009 rule book, in Stock Eliminator, under Camshaft/Lifters: Pushrod guide plates permitted.

I might be a bit late here...but on your trip to Jersey why not leave the heads at Mr. Whitaker's shop? Another good guy in Don Quinn....is he still doing stuff?
