I'm just finishing up my GMC 228 rebuild and separated the intake and exhaust manifolds the other night. I considered not doing this because the bolts were stuck tight and I was stripping them out trying to get them off. Now I'm glad I did it. When I got the two manifolds apart I found that the heat valve was cracked and looks like it's been welded at one time. What's involved with getting this repaired? The shaft doesn't rotate. Are parts available or is this a junkyard kind of thing? Thanks, Neil
