Hello,
:helpme: So I did a thorough search before posting this thread. I could not find the answer so I decided to start this thread. I have read on some internet sites some upgrades that you can do on a 4.0L to get more horsepower etc short of stroking it. I don't have enough funds to fully stroke the engine so I wanted to find out if what I read was true before starting a project. I have a 1987 Cherokee with a 4.0L engine. I am going to be rebuilding the engine over the off season coming up here in CA, starting after Winterfest in JAN. I read that you can replace a 4.0L head with a 4.0LHO head. To gain a little more horse power due to the larger intake and exhaust valves and the shape of the heads compression chamber. I have not yet sought out a 4.0LHO head to look so I visually have not seen what it looks like. Is any of this true?
