BECAUSE FOR $4200 DOLLARS I SHOULD'NT HAVE TO DO SHIT BESIDES PAY THE MAN AND BOLT IT IN. I never did an engine rebuild so I had no idea they wouldn't do the studs. of course they are shot after 50 years and should be part of the standard replacement wore out parts. and they didn't paint it when they were done. I guess I shoulda told them that too... my greater point is that if I spent the same $4200 on a crate motor I would have avoided much wailing and gnashing of teeth. and I would have had new exhaust studs. and a painted motor. and whatever else may come up going forward that I don't even know about yet.
