Stick with the manifolds then. Headers on an off road truck that isn't going to be pulling a sled or mudding or sand drags is overkill. I've got them on my K5 and they are a royal pain in the arse. The collectors leak, the bolts in the heads loosen up and then leak. They make spark plug changing a chore too. I can't wait until I get the 5.3 together and go back to manifolds.

I get reminded of this fact every time we work on my truck over at DirtyLarry's place too. He really hates them.
