I did not see the cross over tube in the screened valley pic. Do you need the cross over tube with a solid roller?
Do you drill 5/16 holes between #2 and #4 main to cam and to rockers?
The pics are a great help, keep them coming.
Thanks
No ncrossover tube, I'm not oiling the lifters at all, and no I don't enlarge the oil passage to the cam bearings for the rockers, they are plenty big enough.
