My manifold is leaking and starting to warp at 183K. I'd like to replace it before a bolt breaks off in the head. 2 or 3 piece manifolds used to be the consensus on 12 valve heads because the warpage could break off the ears on the head. Obviously that's not an issue on a 3rd gen head. I'm looking at the 2 piece DPS manifold and the AFE bladerunner 1 piece as they're the most affordable. Opinions on the benefits of a 2 piece for a 3rd gen?
