rocker studs
 

When changing from stock rocker arms to roller rocker on a BBC does the cocker studs need to be changed as well, for a longer set.

you need to get the rocker studs i think there for 7/16 roller rockers summit or teagues has them.

It has to be changed more for the type of material they are made from and the top of the stud is machined flat for the poly locks for the roller rockers. If you use the stock stud the locks will somtimes come loose because they are not flat enough in some cases.:D

If you have a Gen VI engine, you dont even have studs. You have 3/8" shoulder bolts.

the studs for the stock heads are 3/8 bottom 7/16top

Tony, what are you doin????

That always had botherd me why they went with 3/8,seems like it would be a weak link?

What is the part number for those studs? I never can seem to find them. Good thing I havn't needed many.

I have two Comp Cam sets for BBC new in packing, $40 per set plus shipping. They are at the shop so I don't have the part # now but will list tomorrow

dont know.mine are still stock chevy ones:D

THe only time I need one is when someone has been tightning the poly locks down to hard and srews up the tops. Sometimes I can grind them smooth. I found a donor head a while back and still have a couple left.

The Comp adjustable rocker arm kit conversion part # is 4514- kit I think they use ARPs W/ 170,000 PSI material. 3/8 x 7/16 I have one. If you need it PM me SC

ARP Number is 135-7102
