First thanks to all the good advice on removing the heat exchanges. The MAPP O2 torch did the trick, only one broken stud and it is still protruding about a 1/2 an inch so I think I'll be able to get the stud out.

While removing the HE's to track down an oil leak, I think it is the cooler, I noticed something odd about the HE's. Th PO thought he had put on SS HE's but once I got them off I noticed that the HE itself was SS or some other non corroding material but the connections to the head and to the muffler seem to be steel and at least on the left side corroded. I can move the pipe inside the HE. It does not look like there is any way to fix this but I was wondering if this was a common thing, seems odd to mix SS & steel?

Let em know and I can try and post some pictures.
