So side to side they are within 0.1mm of the other side.
However I got figures of 5.5mm exhaust and 6.3mm inlet. I'm not sure what they should be.
the only sign of any wear so far is one adjuster on the L/H inlet has some marks on it. Everything else appears pristine, however someone has been in at least the L/H side before, head gaskets a different type (colour) and a missing washer on the top stud.
Am going to ponder on whether I just do the heads and put it back together, or pull pistons and do the bearings and rings as well. Doing that also apparently gives visual access to the cam

It doesn’t, cam comes out through timing chest, then followers drop
I’d be pulling cam and followers before moving on if your numbers are even slightly accurate, Much easier to remove rocker pedestal and put dial gauge in pushrod cup OR measure valve travel directly on top collar
Elephant feet part number post #1
Pushrods need shortening to fit, all clearances checked (rockers to each other and to post)
Valve spring installed height depends on pressures with springs you use
I set mine at 75 on seat 150 fully open from memory, crucial that you don’t end up coil bound, no way I could work with Guzzi 2 valve springs for both reasons
Mr Revhead:
Thanks for that.
Yes this weekends job is to remeasure with the rockers remived.
Will see what that does. Was really hoping to not have to pull the cam
75 and 150, what units?

All the hope in the world will not fix it and you have to pull cam to get followers out for inspection anyway.
Half an hour of your life to do, an hour worst case

English pounds, pressure (weight) not currency, yank ones the same, I think

Any update ?
Don’t give up, all will be worthwhile when you ride it
