Exhaust Manifolds

Yeah, I was just curious. I have a set of hooker headers I bought in the mid 70's on it now. Got some surface rust on them so I thought about pulling them and having them coated but the memory of installing them is still painfully etched in my brain. I figured for the cost and ease of install I may look into factory manifolds. I've always run a factory intake just because I'd read multiple articles back then stating none of the aftermarket stuff performed any better other than a 30 pound weight reduction.
