I have a couple K161's off of Model 70 CC's. The exhaust elbows are in pretty good shape, but seem to be virtually fused to the engine block by 60+ years of rust. Are there any tricks to removing them, or should I just leave it? New ones seem to be made out of unobtainium, so I'm afraid of damaging the elbow, or worse, damaging the engine block. I wire brushed the visible threads, and have been soaking them with penetrating oil, but I'm not optimistic. I don't HAVE to remove them, but I'd like to while I'm cleaning up the block.
