Don't buy these=pure junk
I bought this kit as a simple, easy, good-looking alternative to the stock bolts. I read the back of the label, and it specifically states it fits all SBC (among others). I tried to tighten them according to the torq specs and they just kept turning, like it was stripped. I removed the bolt and compared it to an old, nasty stock one I found. Sure enough, the bolts are not as long as the stock ones. Also, the heads are very short, so it makes it hard to get a wrench on the ones in the tight places. So, I will return these and get stock replacement bolts from GM. I will never buy another Mr. Gasket product because there is always some flaw in their product.
Bottom Line No, I would not recommend to a friend
I'd try a different part with longer bolts.

Bummer these didn't have thread sealer already. Also I found them too short. They stripped out of 3/4 end manifold holes. Darn.
