"I have done 3 of them locked up solid with Kroil and a hammer. All of them just once. I consider myself done on all 3 of them."

You had much better success with the hammer and lubricant method than I did Carl. I don't know if Kroil existed when I did the stainless steel shaft and bushing conversion in about 1980. Anyway, as usual, there are various approaches that work.

"If you separate the manifolds, make sure to tighten them to the head before final tightening of the manifold through bolts."

Ed, good point. If that is not done the manifold flanges may not align properly.
