Hey. Glad to find this. Have a 79 CJ with the same motor we're doing a frame up on. Look forward to following mote on it.

I'm in the process of rebuilding my 4.2 258 right now. Good engine.. looking forward to the next round of service.

I just pulled the head on my 90 YJ with the 4.2 and found two pistons with holes punched in them. Not good. Now I need a direction. I don’t have a garage to rebuild the motor.
