I noticed the hole eruption but wasn't sure if it was caused by overvoltage or overtemp. Since the LM338s are since good, it didn't have an overvoltage. The burned off white lettering is a good overtemp indicator. All four of my OPA541s still have all the white lettering after more than a year of daily use.
Maybe you can put a notch in the heatsink for the board or trim the edge of the board so that it doesn't touch the heatsink and will let the 541 mount flush on it.
