360 magnum vs 5.7 hemi

Ok I checked in to my info and the mopar catalog
360/320 - 9:1
360/390 - 9:1 - this one has cast iron heads
360/395 - 10:1 - this one has aluminum head
It doesn't matter much because as of the 1st of 2008 these engine where no longer being produced I got 1 of 2 left of the 360/390 cast iron heads
