Mopar [HEAD] Aches PLZ HELP!?

I dont think it will cost more the$200-$250 to mill the 360 heads down and replace the gaskets.

If the springs on your 360 heads are good you could reuse them on the 302 heads. But you'll still want to have a valve job done. You would have to find the 302s real cheap to keep the costs under the price off just milling the 360 heads.
