O.K. guys, something happened to me today that has never before. About a month ago I removed a 350 from my 1980 c-30. did machine work, reinstalled today. The problem is the pass. side manifold will not bolt back up to the head. I can start the rear four bolts, but not the front two. Or the front four but not the rear two. I pulled it off the truck and tried to mount it to a spare engine and the same thing. It is as if the front or rear ports of the manifold has pulled toward each other. Anybody heard of this or come across it? Wandering if I can apply heat and a big hammer to "strech" it back out?
