Question about heads

I just got an Oasis report for my 04 f350. I found out that in mid 07 the truck got new heads. Here is what the particular entry said:

"CS vehicle is overheating

verified concern found vehicle pushing the antifreeze out of the bottle, performed block gas leak test, was positive for combustion gas in radiator. removed egr valve, still has problem, removed heads and cleaned and checked heads for flatness, found badly rusted around combustion ring R.R. new heads, gaskets, bolts, injector orings, glow plug harnesses, ok"

I've had the truck since Oct. and haven't had any issues with the EOT and ECT delta, coolant leaking or anything else. The EGR cooler was replaced when I bought it.

Should I not really be too concerned with the heads until I go to get studs put in since they're relatively new? Any other insight/ideas?

Thanks

Do the head studs replacement 1 at a time. Folks in your position seem to be having good luck with that and it's a lot cheaper that pulling the heads again.

So do you think that means everything else along with the heads was replaced as well?

OK, I pull the stock studs one at a time, and replace with a ARP. The stock torque spec is much less than the ARP spec. What is the 'correct' method to use for torquing the ARP's?

Put each in and set to stock like the adjacent bolts, and then re-torque all to ARP spec's?

Or, just torque each new to ARP spec's as it is installed? And "IF" done this way do you follow the correct torque sequence?

Just wondering, and that's a wonder in it's self, Si?

Good question as I'm in the same boat.
