I've heard of some people slapping these on 302s...I know the blocks are the same. Would these be an improvement over GT-40s? I have a blown head gasket, and I can get a really good deal on a set of 289 heads, I think the guy said Chevy valves and springs. I haven't gotten a price yet, but he said he'd cut me a good deal for them. Any input from those more knowledgeable?

we definitly need more info on the heads, especially if they have been worked at all

Do you plan on keeping your smog system?

I hadn't thought about that at all, haha.
