I had stellite valve seat inserts put in the T160 Trident I raced back in the 80's
I was running some W&S valve springs and after maybe 2 laps of Amaroo park I'd lose 1500 to 2000 rpm as the valves climbed into the head.
Once I had the seats done (Bernie at Rams Head Service) I'd go from meeting to meeting without having to adjust the clearances.
I think a cheaper option would be to try and source a good condition replacement head though.
