Gl1200 heads: Oil flow

[ekvh]

Other than the diagram in the manual, does anyone have a reference for oil flow through the head of a 1200? It appears to route up to a kidney shaped galley for distribution to the adjusters. I am curious if it also goes straight through beside the upper center bolt to oil the cam or if it goes up through the kidney shape to the tappet adjusters and then down onto the camshaft.

I know the diameter of the orifice on the block side of the head is larger on the 1200. Just unsure of what happens to the oil pathway through the head.
Thanks in advance.
