this may not apply here but I brazed the top holes shut as they shoot oil up to no avail
Those shoot oil to the top of the valve cover to rain down and cool the valve springs
capped the big outer hole on the pushrod side of the rocker where they drilled in
Again, this shoots oil at the valve cover to splash back and lube the cups.
to drill the inner hole to lube the threads to dribble down to the cup.
Doesn't lube the threads or dribble down. Once you tighten the nut, nothing's going down those threads!
Don't like the looks of those shafts !!!
