Junkyard 5.9L Magnum + Edelbrock LA heads build

OK, well double check top and bottom. I have 6 shafts; all have the same sized 5 holes on top, and that same sized hole on bottom in positions 1, 3, & 5, but positions 2 and 4 are larger (on the bottom only). (All my shafts are from the late 60's or early 70's.)

Just be aware..... if there is some nebulous difference in the restrictions going into the 2 shafts downstream of a single restriction, you could get most of the flow into one side and end up starving the other. (It's exactly like any other hydraulic system that way.) With 2 restrictors, each side will be separately regulated, and flow into one won't effect the other...... like the factory did with feeding both head separately.

Good on the testing IMHO. You just need them dribbling....We used the same open top cover trick, running with a drill AND running live.
