I have to agree with Andrew. If the tops of the pushrods were getting
heated I'd say hollows would be a great idea. Since they aren't, you're
just pushing more oil to the top of the head for no reason. Nearly all
stock engines will pump more up there than needed (and usually faster
than it can drain back), so you could be making the situation worse. It
was probably run low on oil a few times. 

Check your 62 TSM and fins out which bolt the oil feeds through. Pull
the rocker shaft and modify that bolt as AMC recommended for the early
232 (see http://www.mattsoldcars.com/techinfo/boltmod.shtml). That
should increase oiling to the head through the shaft where it's needed.
At least I seem to recall the oil going through a bolt like the old
232...

i don't think hollow pushrods would help.  the top end isn't designed
to channel the oil from them to the rocker shaft the way stud or
bridged rockers do.
