Customer approved removal of the HEAVY cast iron cylinder head on this 2001 Jeep Wrangler 4.0L to replace the leaky EXHAUST valves on cylinders 3 and 4.

However, after head removal, it becomes clear that the valves are actually fine!!
However the valve SEATS are severely RECESSED into the head!! WHAT??
Does it need a whole new cylinder HEAD?

The local machine shop didn't seem too surprised at this finding and said they could refurbish the existing head by installing hardened exhaust valve seats no problem.

Will this Jeep get back to full health with the "bulletproofed" cylinder head?
