High Output Head vs Standard Output Head

Searched quite a bit on this without much luck. I’ve got a 2002 HO truck that I Ppumped several years ago and I’ve recently blown a head gasket.

I have a good SO head laying in the shop. I would like to have it worked over before I tear the truck down.

My question is are there any major differences between HO and SO heads?

I know the compression ratio differs between engines which gives them a different sound. I appreciate any input or opinions between the two.

I honestly think the difference is the piston not the head, as well as The pump. The heads should be all the same

This. Pistons are different.

What's the difference in pistons if you don't mind me asking?
