W2 Heads on 1996 Magnum 360 Block

Thank you for that info. Do you know where I can get a 10.5" flywheel for the Magnum crankshaft?

There are available from multiple sources here is a link to one from Mopar Performance. Mopar Performance P5249842 : Flywheel 1993-03 5.9L Magnum V8 | JEGS

Do you need a 130 tooth flywheel?

There are SFI Approved ones available in steel and aluminum too.
