has anyone used arp head bolts on thier ca if so what sort of tool did you use to do up the nuts? i cant seem to find anything that is small enough to fit in the gap but big enough to fit the nut.

Havn't got that far yet, but I was just about to buy a set myself.

Are you using the 12 point head or Hex head bolts?

Even If someone had their engine built by someone else, and still had their contact details.
Any info would be great.

I've read on US forums that the ARP part numbers are mixed up, and some people get sent ones that just aren't right. There was some discussion that some SR20 ones from a different part of the engine might work better.

Not wanting to give you any stress, it's just a thought.

hmm looks like i might have to clearance grind around where the head bolts are. the ones i got have the nut on top, its a good idea because you can put the head studs in before you get the head on but it seems the head wasn't designed to fit the right sized socket
