i bought the ARP head studs aswell from SD parts i think they were like 180$? but they are reusable where as the gm ones are not AND they are rated for nitrous! BUT MAKE SURE YOU FOLLOW DIRECTIONS it took me probably an hour but i cleaned every drop of water or liquid out of the head bolt holes in the block. i guess they can crack if you dont! Spend the money now i guess and worry less about it later... good luck man. i promise your exhaust clip is coming im fighting a damn internet problem at home right now. lightning messed all kinds of stuff up. but i owe you big time I LOVE IT!
