I have a set that I can't use because it's outside of Mazdatrix's specs. I purchased them from Atihun a few months ago but only go started this week. I was told the port was too large. The center was not ported so they used it. I also have a set of Rotary Aviation apex seals they won't use either. $200/per iron & $100 set/seals.
