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?

Did people actually contribute $ for you to buy bolts for your car? Our local food bank will be cutting back this Thanksgiving on the number of soldier families and homeless that will receive food. I guess some are more fortunate than others.
