No heat damage at all. That was only a few inches further so I'm hoping that these will fare as well. Actually my first T/C was not a grounded tip but the thermowell that I made for it is what held up fine. These new T/C's are grounded tip as I welded the T/C wires into the end of the tube with TIG when I sealed the ends. They should work even better as they can't come loose inside. On a side note, last night I did the epoxy-inside-the-secondary-ports modification. I didn't do this originally as I'd had concerns about chunks of it breaking loose and going through the engine, but as it has been several years since this mod was suggested, I would think that by now we would have heard if it was a potential problem. Now I'm considering taking my front cover to work to have the machinist do the "O" ring mod. S.
