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.
