YES. it is running hot... Is the heat rizer a little vacume opperated jobber with a hunk of linkage that closes a flap on the ex manifold? I wiggled it, it's not suck, when I put a vacume pump on the vacume opperated jobber it moves.... wire it open for now? how do i test it?

Have you put a light on it? Sounds like it might have jumped a tooth or two.
Didn't see this before.
Real good advice. It may have moved. All info so far points to a timeing issue imho
How do the new plugs look? Still dark on one side?
Wire the heat riser open. If it still runs hot, drop the exhaust pipes at the manifold, then drive it. Sounds like you may be fighting a plugged exhaust system. Watch out for stuff that will burn with the pipes dropped. Don't hot rod it. You be able to tell instantly if that's the problem.
To test the heat riser, just watch it. It will be closed before you start it. It will open when the engine warms up, just tie it open and forget it for now.

I read your post. The balancer could have slipped on the rubber, thus your marks could be off Have you adjusted the valves? If so when? Did this just come on all of a sudden? I'd start by locating tdc, and pulling the valve cover's and taking a look. I assume this is a sb. Hell ya could have pulled some studs. Really, it is time to get to basic's rather than throwing stuff at it.

Possible causes as I see could be
1) plugs improperly placed18436572 starting right bank front 2) head gasket or broken ring---compression or leak down check 3) frozen vaccuum advance hope it helps..........Have something to add? Share your thoughts — no account required.
