LA heads on Magnum block??

well the oil comes off the cam journal which the cam feeds every time the 3 holes align, which in a running engine is like a rapid fire,almost constant really...

There is a way to tap into the the lifter galley and run hard line [brake line] up between the push rod area and then tap into the side of the rocker stand that normally feeds the shaft.

you can always plug the hole later if you change the heads to something else.

just a thought..
