6.2

It's time for some work on the 6.2 and I'm wondering if someone can recommend if I should have the heads rebuilt while it's down for repairs. I have a small water leak and was going to replace the head gaskets I was also wondering how many miles this engine can go until a full valve job is expected?
Thanks

If you have the money and the heads are off, then it's a no brainer (to me anyway). Get it done and then you don't have to worry about it 5000 miles down the road. Good luck. John
