To All THANKS for your help.

I finished off this project this past weekend and the engine is back up and running. All I need to do now is to 1) check oil flow in the valve galley 2) head engine up and torque head and intke exhaust nuts and 3 adjust valves.

I want to mention that I experienced some issues with the "Hot Spot" on the manifolds. I failed to get a good seal between the two manifolds as both surfaces being rather rough (especially the exhaust). I then tried two gaskets with Permatex Copper Stray without success. I re-installed both manifolds w/o a gasket and saw that the distance between the two was about 1/16" at the wide points.

I thought about investigating locating a place where I could get all three surfaces redone. I decided against that and left it for the "Final Solution" for several reasons 1) porcelain 2) their age with brittleness and 3) the complex geometry of the manifolds.

The approach that I took was to use a long single cut fine bastard file to knock down the high spots on the exhaust manifold being extremely careful not to round the outer edges and to keep things as flat as possible. I knew that this would increase the distance between the two manifolds, but that they would be flatter. So I opted to make mine own gaskets using Remflex's GS16511 high temp gasket material. This is a material 1/8" thick and can go to 3000 deg. F with a 50% crush capability that does not require a lot of torque on the nuts/bolts. It worked like a charm and I would use it again.
