Yes,the 03-04's had some issues but those issues can be resolved. Since you have a '05, you have some issues to work out also, like the STC fitting.
Headgasket failure are usually caused by two issues. The first is when the oil cooler fails, causing the egr cooler to fail, then coolant gets into the cylinders. The other is running a high HP tunes that are not set up to run with the stock head bolts.
You need to find out if your oil cooler is still OK, even though you did the egr cooler delete, if your oil cooler is blocked up, this will not allow the coolant passages in the oil cooler to cool your oil, and this may cause total engine failure when the plastic parts inside the oil filter housing melts.
With owning a 6.0, you need to get something to monitor the key engine temps and pressures. Whether it be a digital monitor or analog gauges, your gonna need to monitor, EOT,ECT,EGT,Fuel psi and if you own a '03-04 a boost gauge.
Before you start adding power, you should start setting up your truck to be reliable so you can enjoy the extra power, instead of being in the shop to be fixed because you chose to ignore the warning signs.
