Which year and/or which model range was it when Guzzi went to unleaded heads...? Just of general interest and after my recent 87 T5 purchase...:augie It sort of slipped my mind...:D
 
i'd have to check, but i think all the tonti bikes are unleaded. if i get a minute, i'll have a scoot through guzziology and get you a better answer :)

i know of several pre tonti loopframes running around on the original valve seats quite happily too.
 
here you go...

i should add that both my le mans and convert have had replacement unleaded exhaust seats, but it was done with other head work. having to recut seats in maybe soft inserts after new guides is not ideal IMO, so the seats were changed.

if you leave them alone, i'm sure they will be fine.
