T800 are you trolling? You've not been a member a day yet and here you are asking some really dumb questions about probably one of the best heads available for high horsepower duramax engines.
If your serious about some of these heads call wagler and talk to them, I've been around here a while and not heard anything but good about them.
There are some really big names running these heads and making huge power on them.
On another hand, it's a 3.0 truck, honestly your going to break shit, from what it sounds like if you have a head failure Jeremy will help you out best he can. Which is probably more than anyone else will do on a 3.0 truck.
