We left off with the manifolds awaiting reassembly.
Because the manifolds were separated, it is necessary to get them lined up before tightening the intermanifold bolts. All bolts & studs have been cleaned & antiseezed. The face of the cyl head will be used as an alignment plate.
Manifold stud after thread chasing:
The manifolds are bolted to the cyl head loosely without a gasket, with all the intermanifold bolts started, and all the gaskets & plate in between the manifolds. The bolts in the cyl head are run in hand tight to pull both manifolds flat against the head, then the intermani bolts are snugged, then manifold nuts & bolts tightened a bit more, then the intermani bolts are really torked. Finally, the manifold nuts & bolts are all torked to spec.
A visual inspection shows that the manifolds are seating well against the head, with a small gap visible at the corners of the exhaust faces. The feeler blade is used to check, and the gap is .012" on the worst, .008" on the other runner. That is acceptable per previous experience and the FSM spec, so the manifolds don't have to be remachined.
The manifolds are pulled off the head, a new graphlex FelPro gasket is hung on the studs, and the manifold is reinstalled for the final time, and all fasteners torked to spec. The fasteners will get re-torked after the engine is run.
The two manifolds appear to be lined up perfectly now.
After manifolds are on the engine, the vac fittings are installed, cooling fan temp sensor, carb studs, heat stove...
