The head gaskets make me uneasy because I don't think they're stock, meaning someone has been in the engine before.
Someone's been in there before, no doubt about that.
A set of TRW 2355's would bump up the compression and weigh close enough to stock pistons that you could think about squeeking by without balancing. They would be a good choice if you were looking at an aftermarket closed chambered head. A rumpety cam like that hughes whiplash really has no place in a truck with efi and a low-cr engine.
