Check the date on the block. I forget what year it started, but Chrysler went cheap **** and removed a bunch of metal from the blocks. When they did that, the head bolts were no longer blind like they should be and they broke through to water.
Pull any head bolt (or a couple) and stick a piece of wire down the hole. If it doesn’t bottom out, you need to pull them all, apply sealer and install them.
If you have an early block and it’s leaking from the head bolts you have other issues, because those holes are blind.
