Default oiling mods

How ya doin? So, 1st I'd suggest getting the MoPar engines book (so much knowledge) & the oil mods I do are; 9/32 drill bit @ 6" drill from main saddle to oil galley diagonal to lifter galley oil passage... & chamfer a few areas that have 90 angles, the method your asking about has to do with roller cam oiling (I'm pretty sure) I've been modifying my oil system for years this way with good results, I also run a 3/8" line from oil pump cover to rear of block (where oil pressure gauge go's) need to modify oil pump cover, also I use factory pick up & 1 external 1, modify pump (Mancini racing sells them) cover for 3/8" fitting ect....good luck
