If that's the case, then I'd love to know how flat the head turns out to be. I wouldn't be surprised if it was badly warped.
Just to be clear, it's not just a matter of them being strong enough to hold (though that's obviously important)
My point is that any time you mix materials, the actual clamping force generated by say 90ft/lbs of torque on each one is going to be radically different between them.
The stud can stretch differently, the threads will deform differently, the friction on the threads can be different, etc. etc.
Since the whole reason for torquing to the same value, and doing it in a particular pattern is to create an even force on the head to avoid warping - it follows that if it's not clamped in place with an even amount of force from each stud, it'll probably warp. Obviously depends on how the head is built too - and how susceptible it is to warping.
I know I'm just preaching to the choir here - but I like to be thorough for people who might be scanning the archives for info.
