No magnums. Ok I'm admit I'm confused lol factory magnums oil thru the pushrods. Correct?
What do you have to do to put la heads on a mag?
As far as that goes how do LAs get oil to the heads ?
I think j par was suggesting "oil through the pushrods" to your question of how to oil LA heads on a Magnum block.

LA heads oil through the block. Up to the rocker arm shaft.
