What happened to ARP's quaility. I put an Edelbrock manifold on with ARP 12 bolts had to loosen bolts to realign. 12 points rounding off. I use chrome finish. Header bolts 12 point chrome finish, one hella time getting them back out. Used brand new Sears sockets. My buddys tried and they pitched a ***** too. The Sears sockets seem to work on all our other projects. I'll be damned if I would even think about using ARP products internally on my engines now. $3000 for my Stroker kit and another $3000 for cam/lifters, block, roller rockers, shims, studs, pushrods, external oil lines, swinging oil pickup and a large modified oil pan. My hardware (nuts/bolts etc) is probably only $500. Big time lost faith. Tried to contact their website twice. Errors/errors in their contact us info. Well contact me @ I won't use ARP products again...
