So my 98 XJ 4.0 decided to take the jump and either needs a new head gasket or has a warped head. Not really sure what the repairs will cost but due to the amount of rust on the bolts holding the head on I'm not pulling the head off myself. So I was wondering if it would be more economical to get my engine repaired or to swap in a remanufactured engine with a warranty or if there was any other swap that I should do to take advantage of this situation. My jeep is my DD btw
