Ok,after preaching the rule for the longest time I looked at some old rulebooks,an as David says there never was any mention of valve cover bolt holes. So I guess that what's allowed in heads now has been legal by the book for years. For some reason I always thought it was in the book. 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?
