Engine builders/Gurus, I need your help.

Good point on the valvecover but it appears to be tapping wihout the cover also . As far as the shaft impeding the flow , that won't happen . What happens is the rockers don't get oil to the high stress area where it needs it. It would be a good idea to pull the rockers and shaft and look for galling ?

I don't know if the hughes rocker is an alum body on the steel shaft , bushed , or full roller on the shaft ???




The rockers definitely aren't hitting the valve cover. As for the Hughes rockers, they're aluminum (un-bushed), on a steel shaft, and as they aren't galled. The only blemish on them is my fault, and that's from when I accidentally tightened the shaft down with a pushrod out of alighnment.

take the cam out and sell it.

and then...............
