Jeep Cylinder Head
Hey, I'm replacing the head gasket in my 2001 Jeep Cherokee that I just bought with 89000 miles. Depending on the condition of the head, I was wondering if any one knew if any companies sell performance heads for the Jeep 4.0L. Tried searching and nothing.
It's the crank sensor!

Clearwater Cylinder Head has a good redesigned replacement head if you want to go with stock.
Also know that if your issue is the head and it wasn't caught soon enough, you will most likely have significant bearing wear throughout the engine.
Educate yourself about the 0331 head. Lots of information online about it. Here is one good link. Good luck and keep us updated!

Without "data", all you have is an opinion!
