I'd say very. I'm buying studs at the moment just so I don't blow mine out. I'm doing 43 with16* timing

43 psi on a stock turbo is just wearing out the turbo faster also.

i am not running 40lbs yet. i just wanted to know. i thought cummins rated these heads for 55psi. looks like i will have to re-tight my stock head bolts to 125ftlbs or more.

Not much point testing what it can and cant take. I blew my first one with stock everything except a fuel plate. And once that oil and water mix its not fun cleaning everything out.
