Some 360 magnum questions

Oooh, 1973dust, you're tempting me to try that.....

I like that alignment tip, I think I have bolts that'll work (I'll cut).

Question: I'm draining the coolant, I was thinking a couple gallon should be sufficient. Will the coolant drain out of the manifold sufficiently or should I do anything special so as not to get coolant in the oil when I pull the intake?
