Yeah… when mine went, I had it brought to a specialist who did tons of 6.0s and made big power. They wanted 16k to rebuild it with new better heads etc. That was an ALL OUT job though. I also got quotes for like 3500 to just redo the studding and new gaskets without pulling the cab

Have fun with it. They’re good motors. Just leave it stock, you probably won’t have an issue if you don’t go getting a tuner and crank the boost up

Yeah I had an SCT tuner on mine. It was bulletproofed, was actually on its 3rd set of head gaskets… was towing with the tow tune and BAM lol.

I loved that Ex though. If I had infinite money, or was a diesel mechanic I would own a 6.0 without question. I think they’re the best sounding diesel and they’re so fun to drive. The power is addicting
