I’m sure their is hundreds of post on the forum about this topic so I apologize in advance. I recently purchased a 1994 4X4 truck and I’ve read that head gaskets are a common problem. Pretty sure it’s been done on my rig already. That being said, I blew a head gasket on the way home from work last night. Not sure if I’m gonna replace the head gaskets again or just do an engine swap. If I was to do a swap, what would be the best engine to go back with?
