6.0L minimum and recommended upgrades

I know this has been talked about a ton. I find things here and there with searching. I have toyed with the idea of getting a 6.0 on a few occasions. I am interested in getting a last year, 2005 Excursion. I like performance, but realize this is probably not the best platform for doing so. If it's rated at 350 hp from the factory, heck I'd consider a downgrade to 300 or even 250. I just want it to work reliably. If I buy one that is factory stock, what are the minimums to allow it to keep it's head above water? Ive heard about coolant filtering issues. Is the coolant behaving or getting overheated? Any change in coolant type show improvement, reduce scaling or whatever is happening? is the factory coolant on OAT (organic acid) or ? COuld a switch to OAT or ? help, or the coolant itself is no part of the issue?I would do some towing up to 10k lbs I guess, but no need for an increase in output. Among other things, does doing head studs over original or already replaced TTY bolts make any difference on a motor with original head gaskets? If worse came to worse and I needed to pull the motor to replace or correct something, what is the $$ range to get things back they way they need to be? I always do cold start observations and watch for smoke or odd mechanical noises. Any particular damage that tends to linger or hide in any of these with a truck that is still running reasonably well or very well and functioning more or less with evil lurking in the plumbing somewhere?Ive read about 6.7 swaps, but my guess is this is still odd enough and low enough demand to not be depended upon as a reasonable possibility? seems like the last improvements to the 6.0 were made in 2007, wish they made the excursion at least into the 6.4 era, but it is what it is. I know 2005s should have already had improvements over 2003 and 2004s. Does this apply to Excursion and the pickups equally? Thanks
