Default Arp head studs. Which one under cut or regular

I was wondering which one are people using and why is one better then the other? Also from previous experience which one would you recommend and why. My goal is about 500-600 Hp.

Are there different versions of ARP headstuds?
I know that Mazworkx got some thicker one for the SR20 guys out there.
LR19 or something like that...?

The difference in price isn't that much for the undercut head studs. If they are better I would rather get the undercut. The L19 requires machine shop work because that are bigger stud like 1/2 inch I believe.

Arp makes head studs that are the same size as the oem head bolts thread but one is undercut design and the other are regular. I don't want different size head studs. I'm just working about the two different design. Undercut or regular design.
