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
