Big block oiling mods

with my SR's I tapped the backside of the fitting of the head and put a restrictor in it. cant remember what size it was ( i think I drilled it to .125" ) ran a single line external pick up. drilled out the passage from the lift feed to the mains to 9/32 and 5/16 on #4.
there use to be a lengthy right up on Bigblockdart.com but I havent been on that site in years.
hell my big blocks are all collecting dust right now.
