Head gasket thickness with F/I
What is your cyl pressure going to be at 18psi on a normal burn? What about when it detonates? Detonation will cause your cyl pressure to spike to 3000+ PSI in really bad cases. That's when stuff starts to let go.
15-18 psi of boost from an ATI F1. will a head gasket that is 0.051'' thick going to blow with that amount of boost. Take into effect that I am building this setup with the W2W 1/2'' head studs. I just want to know if I can run a thick head gasket like that or do I need to use like an 0.030'' head gasket.

Do you mean the 18 psi from forced induction or the 1000+ psi of normal combustion?

boost is irrellevant.
Run what ever gasket you want to, no amount of boost from forced induction could ever harm a head gasket. Detonate the motor at 2" vac and you can destroy a gasket though. Boost is a horrible way to measure things, 18psi of "boost" on your car != 18psi "boost" on another car with 400+ cubes and heads that flow 360cfm at 7000+ DA. It's much better to talk about head gasket reliabilty at a given horsepower level.
Your biggest concern will be lifting the heads at the 900-1000 HP level which I still believe is caused by mild detonation (cyl pressure spikes) on most setups since it is often cured by backing off the timing 1-2 degrees.
Mine lifted at a lot lower HP level...~750 flywheel.

As others have indicated, detonation etc will kill any gasket regardless of power or boost.
So keep the tune safe, and it will hang together, assuming its a decent build.
I ran my 382 for over a year, and about 10,000 miles before I had a problem, and that was lack of meth related...hence detonation.
No idea of power though, but it was trapping high 140's on pump fuel+meth

Not the brightest idea.
