There seems to be 2 types of head studs for the 2JZ, standard vs U-cut.

Which one should I get ?

I got the U-Cut ones which HP Freaks recommended to me when I asked the same question of them. I think it results in a more even torquing of the head?

I also heard the U-cut but dont know why??
More even clamping force.. it allows all the bolts to stretch a certain degree before max torque/clamp to give a more even load. Otherwise, the bolt, once torqued, will stretch even further under load, causing seperation of the surfaces. Pre-stretching them prevents most of this from occuring.
