Guess that makes all the b,c, and d cares with vc bolt holes blown through illegal now. And since the rule never said anything about vc bolt holes in ss ,doesn't this effect Chevys too? Nobody never noticed that except for Barton? Oh I know it was one of those unwritten rules right?

Strange but?


My 2000 rule book states the same thing as my 2011 rule book

Stock - Intake side of the head may not be cut into any part of the valve cover bolt holes

Super Stock - Requirements and specifications for all Super Stock categories are the same for those as Stock with the following exceptions.

With no mention in the Super Stock section allowing cutting into the Valve cover bolt holes.
