Leoni cyl. heads

[coloradodutch]

Ok so i have a set of springer 860 cyl.heads in very good condition ported by Reno Leoni complete with valves springs and stock cams. set up for 32- 36mm carbs. I have been setting on these things for 20 years may be time to part with them.I also have some Reno-westco 11-1 87mm pistons. I have no idea what they are worth.any one want to make me an offer?

No idea re value,but a quick question: Is the surface on which the valve spring pack rests fully formed (round) or is it "partial"? " My 750 heads were only partially formed there (after all the Desmo was what everybody cared about,right?),and this and the 10mm long valve guide bores always scared the dickens out of me when the heads went into racing use,altho they never did explode.Jerry branch had done those heads,and when he said he thought they would "be okay",I felt better,but I think now I could have/should have welded and machined that valve spring surface pretty easily.

I don't Know much about 750 heads but on 860 's the spring seats are completely on the aluminium. The advantage of springs are more cam options. Were your heads orginally desmos?

[Ray O'Donohue]

My heads were springers from the outset.Many more sprung than desmo bevel twins were made in the early twin days,but Ducati being beset with so many problems at that time simply surviving and building batches of machines,nothing is surprising.
