Is a 5.2l cylinder head inter changeable with a 3.9l?

Considering there's an extra set of pistons, I'm leaning towards a solid no. V6 has 3 pistons on each side, 5.2 V8 has 4 pistons on each side, making the heads longer. You'll have to get one from a 3.9. Lucky for you, you have the choice of 92-03, those were the running years of the 3.9 Magnum.
