ARP is worth the price if you like the attention to detail they pay to their fasteners. They are definitely the cats azz if you prefer both max performance and great looks. I prefer GM fasteners on a restoration because there's no doubt that while they don't always look perfect, I know they will function as designed and engineered and they are more "correct". Just depends on what you're going after.
With that said, I've used ARP studs on 455 main caps, and other fasteners I considered critical during a warmed up BBO assembly. But...I don't think I'd waste the money for holding on an HVAC delete plate unless I was building a show car. In America, though, you certainly have that right to spend your money as you see fit on your car and buy the bolts you want.
I forgot that the plate would play a major role in keeping the engine torque in place. But.....how about ARP to hold the speakers?ARP is worth the price if you like the attention to detail they pay to their fasteners.
