I'm rebuilding my 6.0 and am wondering are the piston and bearing coatings worth the money. I was quoted 1,000 to coat everything. Is it worth it? I know it looks good on paper but does it really help with anything.

IMHO, if your running stock components and stock power it isn't needed. If your not running the drag strip I probably wouldn't bother.

That's what I was thinking. I'm definitely not racing it. I do have bigger injectors and a power max.

Coatings work, no question about it. If you look at max effort engines in any sport they are going to be coated internally. But, for a typical street engine they are IMO overkill. I would suggest thermal barrier coating on the piston crowns, and anti-scuff coating on the piston skirts, but if you're using OE pistons, which I believe are Mahle, they should come coated, as Mahle was an early adopter of coating technology. Beyond that I don't see much benefit for the cost.

They are Mahl pistons. The skirts come coated from the factory. My machine shop offered it to me. I turned them down. It seemed way overkill for a daily driver

Instead of the coating I'm installing a reground cam. Stage 2. It's suppose to be easier on the valve train. Lower EGTs and fast spool up.

If it is a Colt cam, I believe the Stage 1 cam is the regrind and the Stage 2 is same profile as Stage 1 but is a new core cam. At least that is how it was explained to me.

It has a bit more of an aggressive profile than the stock regrind.
