How do you get LA heads to oil properly with a magnum block?
drill horizontle into the rear of the head thru the threaded boss to the rear pedestal then spot face inside the pedestal in the threads to get a hole started to drill downward at an angle to meet the hor passage. Feed it from the oil psi sending port at the top rear of the block & T off of it to feed both heads. I'd have to check my notes but iirc I drilled an .080" passage at the top. This is a good mod for ANY eng as it lets you restrict the 5 vertical passages from the crank to the cam to 1/16" (drill/tap for a setscrew and drill the set screw to 1/16") as that is all the oil the cam bearings need and cam bearings are a major wasted leak point and contributes to oil starvation probs on rods fed from mains that feed the rockers from the cam (#4 on a BB)
