I'm swapping heads from my 806s to 243s. The 243s are bare, but I would like to (if possible) swap all my stuff from my 806s over to the 243s. The main thing I need to know is what machine work will be necessary (if any) to swap the valves and springs etc. over to my new heads.

 

I dont see why you wouldnt be able to do that. Have you shopped around to see how much a set of valves would cost you for those heads?

 

Well can't I just reuse my stock ones in the 243s?
