ARP Bolts, Proform 950 and Valve Covers

Sorry about that....I should have been more specific. It was a little late last night!

The carb was an 850 Holley that was upgraded using proforms base plate and body.

Here's a close up of the underside of the valve covers. It says Chrysler and the numbers looks like 644. Not sure, I'd have to verify this when I get home after work. I pulled these off my 71 Charger that the original owner had put on just after the purchase of the car, probably mid to late 1971 from his recollection.
