: BB head bolts with original socket head size

Dec 18th, 00, 10:24 AM
Anyone know where to get BB head bolts with the correct head size? I have a 1969 427/425 that has ARP head bolts with a ˝ socket head size that I want to replace with original head bolts. The parts guy at my local Chevy dealer said the only ones he can get have a 9/16 head. I think the originals were 5/8 or 11/16. I tried a few places but they all said they couldn’t get the larger head originals.

try an industrial distributor, socket head cap screws have two standards, they should be able to help you. hope this helps.

I purchased mine thru our sponsor - Ground Up - page 35 in their catalog, they were exact to my originals.
