0331 Head

[akadeutsch]

So, my 2000 WJ has 212,000 miles on it. I have done regular maintenance on it but it is still starting to smell like burned oil and puff blueish smoke. It is time for a rebuild. Why not build a stroker I thought? In my research I have found that I possess the shity 0331 head. Like I said it is a 2000 Grand Cherokee, is there any other year head that will work on my 2000 block? where do I get it?

I found an 0630 head for 100 bucks. It came off of a 99 Cherokee sport. Will it fit my 2000 WJ 4.0?

Any 4.0L head will fit your block. However a 03-05 0331 head will work better with the stock exhaust manifold as well as the coil rail mounts. Its not recommended to use the stock exhaust manifolds on a 7120 or 0631 head due to port misalignment.

thanks for the help. I'll start looking for the 0331 Tupy head at the jeep yard
