Going to swap to a manifold set with working heat valve.
Understand a few things reading old threads. But also some questions.
1) check for warpage with straight edge
2) connect intake to exhaust only loosely until snug to block
3) install gaskets on block --- no special goop?
3.5) any sort of anti-seize on the bolts?
4) tighten in shop manual sequence. I don't see any way to get a torque wrench on some of those bolts?
5) tighten intake to exhaust connection
Bumping an old thread. How much warpage of the manifold surfaces is too much?
I've got a manifold pair with a working heat valve that will replace the one with a stuck valve. If I turn it over, and lay a framing square across it, I can see maybe 1/32" (eyeball test) of daylight on a couple of the exhaust surfaces.
My theory is that minor gap should close up once I loosen the two manifolds from one another and torque it up to the head. Between a little bit of flex in the manifold and the gasket thickness...that I might be OK without getting them belt sanded.
What do you all think? Worth trying it as is, or need to have the surfaces milled a bit?
