Your local Pick-n-Pull should have an entire Magnum 360 4 around $200....
If you get Magnum heads you're going to need an intake manifold for a magnum. I bet by the time he bought Magnum heads you could just go ahead and buy an entire 360 Magnum. And then all you would need is a manifold. You'd probably need a couple hundred dollars worth the accompanying Parts but then you would really have an upgrade..
Food for thought and that's probably what you're looking for food for thought...
