Mild 360 Magnum Build

If using a magnum block, rod and crank and putting a la piston on it, wouldn't that give you a positive deck height.

Not necessarily. That depends on the height of the piston.

I thought that the deck height on the Magnum was less than the deck height on the LA.

It is but not by much. The exact amount will vary as the LA engines did not always come with a uniform Deck height. The magnum was much better at this.
