ARP main/head studs

Hi guys,

Starting to mock up my 221 and noticed that the ARP studs I have for the head and main caps are exactly the same, the boxes aren't labelled so I just wanted to check if this was okay or if I might have been shipped two of the same stud kits? Have got the block fitted in the car at the moment so I'm not able to check the fit of the main studs

i may be wrong, but it seems to me that on the six, the head bolts, and main cap bolts are the same.

correct. my old turbo 250 2v was main and head studded.
they are even long enough to use a crank girdle as well.

Turns out that the 250 uses the same length studs for mains and head but the 221 and I assume 200 use shorter main studs. I got a chance to check and the non threaded section of the stud extends past the washer flange on the main cap.

If there's anyone down under that wants a cheap set of main studs for a 250 or head studs for any small six let me know, its not worth the cost of me shipping them back to the states for an exchange set

Cheers
