LA heads on Magnum block??

you could tap into the sender port at the rear of the block then T & plumb to both heads & drill horizontally into the rear end of the heads then drill down at an angle up top from the threads in the rear pedestal(s) to plumb em that way. It'd be full time oiling as opposed to cam timed oiling so figure out what size orifice you'd need for the right amount of flow. I do have a set of bare EQ's (LA pattern) from Eric Haugland in Las Vegas, reasonable price/nice heads/good guy to deal with.
