  I would look into getting 85-85 GSELE rotors with the 3 mm seals, you would also need the weights to match them, then machine out your rotors for a spare engine, you may need one to bale you out in the future, if you keep this up you may knock me off the seat as president of the dead stick club.
  I am now running rotors machined out to 3 mm seals and at about 400 hrs on them I can tell by checking through the exhaust port that the seal grooves are getting V'ed out and getting sloppy so I am now putting another engine together, on this one the rotors are in prime shape so I think I will run Tracy's 2mm seals.
 Also I think that the groves may be hardened and by machining the groves out makes them softer as they shouldn't have worn out in only 400 hrs.

Well, the decision has been made.  Thanks in part to the wife's continued interest in my warm body on  cold winter nights, the decision has been made to purchase new rotors and rotor housings.  $$ but apparently I am worth it {:>)
 
I looked into milling out the slots to 3mm and that would have been the cheaper approach - but cheap approach is probably partly responsible for me being in this situation - so going to try a different approach this time.  Besides leery of using a rotor which clearly has been subjected to sufficient loads to scrape metal off its surface and peen over apex slot.
 
In the process of getting quotes.
