All good info, thanks. Yes I know about the studs- the black ones will be going back in if theyre not there already.
Still not clear on the V2 big valve head, from the dates in that post No19, wouldnt all Monsters have a V head?

So Just to clear this up

W - 750/900 small valve Hemispherical combustion chamber OR/VR Cams
V - 900 big valve Bathtub combustion chamber OHT/VHT Cams

From january '92 up, all engines came with aluminum-bronze (replacing the cast iron)
valve guides and a "V" on the heads,

V1 revised valve seat
V2 had revised oil feed
Unsure when the crossover was but
V3 late injection 08J/V8J cams head is fully interchangeable with V,V1,V2

Some heads manufactured prior to 92 were revised at the factory so it does get confusing as its possible to have a 90/91 manufacturing date on a head that has 1992 spec

The cam id used is what they came out of the factory with don't take it as gospel as many people swapped 08J/V8J into earlier heads or if lucky you might find OHZ/VHZ (ST2) or GMO9/GMV9 (Ducati Performance)
