i just about done installing the upper and lower manifolds (performer 5.0) there was about 4 holes in the lower manifold that needed to be plugged, 2 holes that came out of the box with stripped threads, the adapter peice needed to be drilled out, didnt come with lower to head gaskets, and just was a pain in the ass. also there is a bolt that has to go in through the capped off end of the upper inttake. all i have do do now is figure out where the skinny vaccum hose thats under the manifold goes, and i cant remeber where the FPR hose connects to? theres a hole on the egr, and then 2 little holes on the vaccum tree on the elbow, is it one of those? and then get the idle right and im done.
