Possible oiling concerns

If you do remove the existing rocker arm shaft, take the time to get a good look to see what direction the shafts oil holes face. That cylinder head does not have a lot of sludge build up, so it is possible that someone has previously had it apart and did not orientate the shaft correctly.

So I just got home and got the rocker shaft off. As i removed the rocker shaft bolts I heard what sounded like a squirting noise. Is overtorquing the rocker shaft bolts a potential cause of poor top end oiling? The rockershaft itself is rather well coated in oil… curious. I’ll check for oil hole orientation as you suggested and get back to you
