Ahhh i missed that 
Well I got the 6.0 broken down over the weekend. Everything in valve train was mint, almost no carbon on the pistons, BUT there was some coolant in cylinder 7 at some point.
So I'm waiting on a quote from the machine shop to see if they can just hone it out. If not I will have it punched out to a 6.2 and use OEM LSA pistons; or if the price is right it might morph into a 408ci
I'll also have the heads tanked and cleaned up too.

Is there some pitting in that cylinder? Was there a leak in the headgasket? Or 1 starting? How can you tell there was coolant at 1 time in it? Just curious.Well I got the 6.0 broken down over the weekend. Everything in valve train was mint, almost no carbon on the pistons, BUT there was some coolant in cylinder 7 at some point.

Vary mild pitting, so mild that the leak down test was good. BUT I'm OCD and honestly gives me a reason to go bigger LOL.
Cylinders 1,2,3,4,5,6,8 were 0% on the leak down and 7 was only 2-3%. I honestly think I could throw it back together and be fine........but it would always be in the back of my head. Not only that I only want to R/R one time
In regards to the head gasket, not for sure or certain. The combustion camber did not present any evidence of a head gasket leak.
