.030 5.9 magnum

Yeah its a magnum. It has a balanced flex plate with tone ring. Everything on it is magnum except for the pistons apparently.

Kb107 with the heads list above should net the ration I want right?
I'm going to go ahead and pull a piston to make sure everything else is okay I.e rods, bearings, crank..

Also with the kb's would I have to balance my crank?
