440 Oiling mods

I like the oil mod that moparteacher posted on big block dart with pictures I run oil through lifters and push rods.I have not had any trouble with 440 source rockers and shafts.I did have trouble with a set of heads but they sent me a new set Any part in a gas engine is prone to brake.And all most any thing you buy to day is made in china.You mis a gear at 6500 you will have a bad day And when some one has a bad day & you keep pushing they may say somethink just to shut you up.I have broken rockerarms by try to get things to close over reving and using the wrong part for app.
