Question about ARP studs

I have been trying to tighten the ARP studs that I have, but can't seem to find the right socket. After alot of searching I went to sears and purchased a 14 mm 12 pt deep well socket, but the damn thing won't fit between the crevices on the head. I can't even get it on half of the bolts. Can someone help me out here and give me some pointers on this?

grind really? That sucks. I do not have a grinder. Would someone like to sell me a socket?

Try removing the cams. I didn't have much difficulty installing the studs.

No. They are 12pt 14mm and I bought a craftsman 12pt deepwell socket and it worked fine. It barely fit but it worked. Just make sure you use the arp grease around the sides of the socket so there is less friction between that surface and the head...this will ensure a more consistent torque value to each stud.

no... they are 1/2 inch 12pt

14mm is close but 1/2 inch is the proper socket to use

I used a 14mm 3/8 drive ground down slightly. I felt a 9/16 fit sloppy and I didn't want to put putting 85 pounds of torque on a fasterner without a tight fitting socket.

FYI, a 1/2 drive socket will not fit into the head casting.

I would be a bit nervous to use a METRIC socket on a Standerd Head bolt

I'm going to go out.. and put a standard socket on the head of these studs I've got to see whats up.

I'll tell you now, I put 85 pounds of torque thru a slightly ground down 14mm socket. I bought an S&K 9/16, 1/2 drive deep well that didn't fit. Hence hte need to grind down the 14mm.
I'll check it out later tonight if i think about it.
