Exactly the trick I was looking for inside the cover. Thanks.

Thinking to replace those lower pushrod tube spring clips with S.S. hose
clamps.. Thoughts?

I have sealed the leaks at the outer end of these tubes by removing
only the rocker cover, squirting some strong thinner (like laquer
thinner or brake cleaner) into the joint, and blowing it out with
compressed air. Several applications like this gets all the oil out,
then a wicking-type threadlocker like Loctite 290 will go in there
nicely and harden up after a bit. No more leaks at all. Don't let
Loctite get into anything other than the joint, though.
The inner ends of the tubes may need those boots replaced. The
cylinder base nuts have to come off and the cylinder backed off a bit
to get the boots in, but then the cylinder base seal should be
replaced too and that requires the jug to come right off.
