yeah, I dunno, I always heard camel humps were nothing special, but I'm not a chevy man so it's all hearsay anyways.
but, I did have a set of heads rebuilt by a speed shop once. "give em the works," I said, "these are going on a race car." yikes! you have no idea how much fixing up a set of heads can run. sometimes it might be cheaper to buy the aluminum heads that are ready to rock n roll than to have an old set fixed. be careful...
