Update:
Barry: I used the Blue thunder thick gaskets (which I can't find on their website). Removed carbs to check intake runners. All look good with no signs of leakage, but I notice they want to separate (they are two gaskets glued together). Where the intake joins the head, all gasket edges look good with just the smallest bead of gray sealer showing on both sides. I also noticed the right side plugs are slightly wet (
oil).
I installed a PCV in the right V/C, but havent run the engine yet,still have other things to ck. Thinking valve seals.
