Help! I am in a world of hurt. Installed Springfield exhaust block off plates and I guess one of the gaskets moved enough on installation that I have a major water leak . The black RTV has now set so hard that I can't get the manifold off. Any suggestions ??

Fred,
The Olds china wall to manifold is .080~.090 (if my memory serves me..), so, yes, the smart thing to do is cut as much of it as you can with a single edged razor or a box cutter. Wet the blade and it will be easier - Armourall will work even better, but be sure you clean it all of before reassembly. The RTV will cut, but with some effort. It is not all that wide (if you recall), but once you get it cut through, you should be able to push a screw driver point in there to make the rest of the cutting go more easily.
JUST DON"T RUSH.
As someone else said, do not pry in there as the casting may fracture even at that light load.
