No oil to top end

As mentioned, the rocker shafts get 2 spurts of oil for every 2 crank rotations .
For every one cam rotation, you get 2 small squirts of oil, only when the cam holes line up ! !
There is no steady flow of oil to the rockers .
You have to line the holes up to get flow as mentioned in post 6.
I'm not sure of the (*degrees quoted tho) but definitely in only 1 specific location for each side .
