235 Exhaust Fastener

Working on a 1953 6400 with a 235. Went to remove the lead pipe. Normally I'd split the nut to get it off. Not sure what I am looking at but does not appear to be a nut. Could be a hex shaped spacer with a 5/16 bolt (head is 1/2" not 9/16 but spacer or whatever it is is 9/16) threaded into the manifold or some type of JC Whitney latest and greatest exhaust fastener fix. Anyone know what I am looking at. Obviously don't want to break off in the manifold.

Having technical difficulties tonight will post pic in the morning.

My 235 has studs screwed into the exhaust manifold with nuts that tighten the flange to the manifold.

Thank you for the picture tip, you read my mind. The stud/nut is what I expected but found something else.

From your picture it looks like a bolt head and not a nut as you would expect. There are two possibilities. Either the PO drilled out the original stud due to it being snapped off and used a nut and bolt in place of the stud and nut or they were able to unscrew the worn stud and used a bolt in place of the stud.

If it is a bolt screwed into the original threads you best soak it with PB Blaster or Kroil for several days before trying to remove them. Even then it may be necessary to heat the area around the threaded section with an O&A torch to get them to move. If you can get them to move, don’t try to muscle them out, but instead finesse them out by soaking, tightening, loosening a little at a time and repeat.

This is what it should look like.
