Ive seen it first hand out of Steen Racing on two separate occasions when I worked with them.
I will play. Below are a couple pics of a L92 head that was under a S480 turbo @ 12 psi, car was making 650ish belonged to a buddy of mine in Va. This is the direct result of pushing L92's to far with a power adder. When you push these heads past the 600 RWHP range they don't handle it well or for long there are always exceptions to the rule but not many, This motor also had 1/2" studs and LS9 head gaskets. FYI.
Doesn't matter if you go turbo or nitrous the end result is more cylinder pressure and this will eventually be the result.
