A lot of things have been written up on big block chevy oiling systems and we have a wealth of very good engine builders in this site, some of the things you can research on the web or even right here are some of the following mods,
edge orfice lifters
oiling restrictors
oil pan baffles and deep sumps
swinging pickups
and a whole plethra of other stuff that fellow members can expound on

grind the oil valley hole to a tear drop roll the top of the top of the cam boss if you look at my block. you will see the front and the back in the valley how i made this smooth you can drill one 3/16hole in the back by the last hole in the valley this helps drain back and helps add oil to the cam gear and i grind in the oil rails i round all sharp spots i use first stone and then go to sanding drums

you have a pic of the hole above the cam gear? i dont see it in that pic.

carbide burrs, stones, and sanding rolls are my freinds.
