That is a very vague question that is subject to a lot of variables.
Simple answer is NO!
Do some digging around (research) and you will get some detailed information, understading and knowledge.
For the most part if you are responsible with the power you will be fine.
The leading contributors to a blown head gasket from what ive seen are:
A) running it hard on a cold engine ( hot rodding before it's up to operating temp). If towing big loads let it warm up too.
B) High EGT's
C) Excessive Exhaust back pressure spikes (EBP) (keep that below about 45psi to be safe)
D) On the flip side, overboosting (stock turbo is only good for about 38psi before it loses efficiency and creates more heat than power)
I run the H&S Mini Maxx on wild (120hp) with no advanced turbo tuning (ATT) daily and up it to the Hot Damn tune (175hp) on road trips for fuel savings. I set my defuel for 32psi so that keeps my EBP in check when I am driving a little spirited. The advanced turbo tuning tune (defualt tune) is a little more responsive, but my EBP was spiking around 50psi pretty quickly and easily at only 26-28psi of boost. The Non-ATT tune is closer to a 1:1 ratio (boost to EBP) so even when I need to pass someone quickly and my boost pressure shoots up to mid-high 20's quickly my EBP never goes above 40psi.
Head studs never hurt though... What are your plans for the truck?
