Can anyone identify the manufacturer of this head stud? It fits our C5-R engine. It has the hex- notch on one end and the other is round. Thanks.

I'd say ARP, but usually their logo is stamped into the stud, and the round end should be flat, unless that's an older or recent design change.

I do have some from ARP and as you say, flat, also no hex and the NC threads are shorter, also the body is not so necked down. George

The ARP main and head studs I had had a hex hole in one end so that they could be threaded in.

A1 Technologies makes the original studs to the best of my knowledge. The thread is american not metric.

Yeah....A1 Technologies......I spent 1000.00 on my studs for my C5R...290 tesile strength...made from metal called MP-35..

What I noticed......did you buy the block used?? To my knowledge A1 Technologies does not have the allen in the end......but they do make all the C5R fastners..

Thanks Guys, A-1, Found them late last week and picked up the bolts from them on Friday, Just up the road (SoCal). Very nice people at A-1.

Picked up the complete engine used, ran it for about a year, now doing a valve job and changing the intake.

There IS a hex inset in the end.

Thanks,for the replies. George

Now if anyone can help me with my injector question.
