Need advice
I got this 2006 6.0 287,000 for free because it was backfiring out of the intake. I found a broken exhaust rocker and I’m taking the cab off some time next month to fix it. I wanted to tackle some of the other things that go out on 6.0s while I’m in there. Is there any parts that I need to replace or upgrade to make this thing more reliable and bulletproof it? So far I plan on doing ARP headstuds and better head gaskets. Any advice for a parts list would be greatly appreciated.
