500 cylinder height

Can anyone give me the cyinder base to head gasket surface height and the crank center to cylinder base?

Barrel thickness?

Isn't this the same as others, or is it unique to 500 cases?

Without gaskets, just the components? Not to be semantic, but just want to get you the right numbers, if possible.

Yes just the 500cc components not including the gaskets.

My three measurable barrels vary in height between 4.250" and 4.240", but have a consistent height individually. At least within the accuracy of a pair of nice calipers measured half a dozen times around each, not on an inspection table with a height gauge, or any actual measuring protocol. All are dynamo and spigotted, and relatively clean.

I don't have a case in a measurable state right now.

All the heavyweight twin crankcases should be the same height from main bearing c/l to barrel bottom face. It would have been an unnecessary change for Norton to make them different.

Thanks. I'm laying this out in autocad so I can keep track of the piston to valve clearance.
