A few pictures would probably help a lot. We may be able to come up with a fix.
So a couple of pics of the epoxy fix.
The pics hardly tell the story here as they don't seem to show all that much of a difference in the diameter of the pushrod hole, but it's there. With my 5/16" pushrod checker and the rocker arm centered over the valve stem I am maybe 0.005-0.010" away from that epoxy...so moving to a 3/8" pushrod I am going to need about 0.030" extra room (5/16" is using 0.152" distance from the center of the pushrod, while 3/8" needs 0.188").
Really, the 3/8" pushords are supposed to be ready by mid-week...and that'll ultimately tell the story.
