I want to figure out a way to just put la heads on a magnum! I have 2 extra sets of heads just laying around. Getting the oil up is the only difference right?

I noticed this note on the new trick flow head.
Might look into it for standard LA heads.

Magnum engines must use Harland Sharp S72025K (1.5 ratio) or S72026K (1.6 ratio) shaft mount roller rocker arms for proper oiling.
