Exhaust studs too long. Solution?

[Fidalgo911S]

Currently replacing the SC exhaust that was put on my '74 prior to me owning it. I bought a set of used '74 HE's with the thin flange. I'd say the exhaust studs are about 3/8" to 1/2" too long.

Do I just stack washers on there or is there a better way?

[Oh Haha]

Cut them down with a Dremel tool with a cutting disc. That is, if you can get to them easily.

put nuts on first and then remove them after cutting to restore the end threads.

I was just gonna say, buy new ones.

Engine is on the stand so cutting the studs down will work. I think that's a good solution.

Is there any chance of you changing the exhaust out again? Maybe the new exhaust will have the thick flanges??? I always try to keep things the way they were, in case I ever decided to put things back how they were. I would not cut the studs, because I might need them the longer length later. I would not use washers to make up the difference, I would use sleeves, that would make the studs the correct length. Or as another said, get new correct length studs, and if you change to a thicker flange, put the old studs back in, if you kept them, but new studs and nuts would be better. Just a thought.

People who have used sleeves for this, are you just using something like stainless tubing. Is there a fairly accurate length to use, or is it YMMV?

Removing the studs, unfortunately is not an option. A couple of them broke when I disassembled the engine and the machinist had to drill out the remaining portion. Even welding nuts on them and using a big wrench didn't work.

I tried sleeves, but unfortunately used a soft material (brass). That took an hour to undo. I like the idea of keeping the extra length. Thicker steel sleeves then. I imagine I'll have to cut them to length.

A stack of washers is the good solution.
