ARP makes great fasteners. What type of advice are you seeking?

Studs are easier on the threads, which is especially valuable in an aluminum block. They are installed with minimum rotational force. Secondly, studs provide an even and more accurate clamping force because they do not suffer rotational torque, only vertical torque. As a result, they can be reused frequently and are a hell of a lot easier to tighten, and remove.

The reason I am asking, specifically about the bolts is... everyone is back ordered for the studs, with no exact answer as to when they will be back in stock. The ARP bolts I can get right now.

Seems like your choice has been made for you if you wish to proceed with your project in the near future.

The GM bolts are a lot less expensive and work fine. If you’re planning future tear downs, I would go with the GM bolts to get it done now, and buy the studs as soon as they are available for next time. I try to have all my parts on the shelf (in the very back of the shelf hidden from you know who) before I begin work. Hoarding parts is part of the fun, lol…
If you are using GM bolts be sure you have the tools needed to follow the torque to yield instructions.

GM bolts, ARP bolts and ARP studs all work well. I agree with using studs for the reasons above and have used them on my builds. From a perspective of handling power / cylinder pressure all 3 would work great on my heads and cam car. I like studs as the chances of pulling the threads out of the block and needing a time sert is much lower.
