In my experience, I have to disagree. I've been running these motors for about 7 years now, and have never had that problem. They are VERY stout. I even ran a stock turbo at 23 psi for a bit with no problems! Talk about RIGHT NOW torque. hahah
Plus, mine has ARP head studs...
Turns out they're even cheaper than factory replacement head bolts!
