Root how bad were the cylinders. I had the same problem with the 2004 84K motor I got. Guess the po thought it was a good idea to pressure wash the engine with the sparkplugs out of one side. How ever I was able to get the pistons out after soaking in mystery oil for a couple of days. Then a light hone cleaned them up real nice. The pistons also cleaned up nice in my parts washer. I also lapped the valves myself and put it all back together. Still runs good after 8K miles and burns no oil. Also used ARP head bolts as the stock ones are one use only.

Other that the what you mentioned, does the rest of the motor look to be in good shape?
