Got the passenger side exhaust manifold on no problems. Went to put the driver side on only to find the threaded bolt on the donut end of the stock manifold hits the steering box. Not a big deal just need to get the threaded bolt out and it would then mount up with the engine. Only problem is there is no way the exhaust can be connected to it there.

Since I promised my wife to some other commitments in the afternoon, I tabled doing anything for now. I did pull out the Sanderson header and tried to fit it, but the clearance between the steering box and exhaust flange won't clear unless I loosen the tranny and jack it up with the engine a few inches. It should then clear and bolt in. The header is designed to work around the stock steering box, so it sort of tucks in close to the block and exits towards the front of the bell housing with enought room to plumb around stuff.. So I'll wait until I have some more time and help and just go ahead and permanently mount the headers and take my chances with discoloration.
It was nice dusting off those headers with the silver ceramic coating they look almost like polished aluminum. Oh well in the hot rod world these things happen!
