I gonna start tearing my car down here in the next couple weeks and need to buy head fasteners to put it back together.

I will be running stock 317 heads with GM MLS gaskets. Goal is 550-575 rwhp and roughly 10-11 psi.

I know ARP studs are ideal but the big goal here is budget. If i can get away with ARP bolts or even stock GM bolts it would be fantastic, but if not i dont mind spending money on things that are required.

What do you think

i consider arp studs being required on any FI motor with 4 bolt heads. but that is just my personal opinion. there are plenty of people running factory head bolts on 8-10 psi

man, if i where you get the ARP studs, I'm pushing water with 12psi with arp bolts. going to have to pull my heads and redo it with studs, i do have an ls2 i am building up..so might hold off to just swap in the ls2.

ARP bolts worked fine on my 347 pushing 15psi.

ARP studs, for the cheap insurance and better clamping force.

There is certainly no reason besides budget to avoid upgrading to ARP studs.
Budget and FI are very rarely used in the same sentence! (besides this one lol..)
Future in-car cylinder head removal will also be much easier.
