Stock 2G head studs stronger then 1G head studs?

Since the 2G's run more boost and have a higher compression ratio, do they happen to have stronger head studs then the 1Gs? Just wondering...

they actually have weaker ones. 2G's use stretch bolts so you need to change them anytime you take them out. if you have your head off just get ARP studs.

Yes. In addition to the stretchy bolt factor, they are smaller as well. 7 bolt is 11m vs 6 bolt 12mm. Even with ARPs the rating will differ accordingly.
