As has been pointed out many times on this list, the original feed
through the block is limited on purpose, and for a reason I might add.
I would definitely advice against adding an extra oil feed to the rockers
if your engine does not have valve seals.

Are you really sure that the leak is from the head gasket? That is quite
uncommon. It is more probable that it actually is from the rocker cover
gasket due to the increased amounts of oil now present in that area.

I find this slightly unlikely, since there is a compressible copper washer
in the head around the feeder hole that should take up any unevenness.
