I don't know what lengths this kit has, but ARP says B1 wedge.

EDIT:
Wow, ARP responded quickly to my queston about the stud lengths in that kit 145-4007


I bought a used set from another racer, and those studs were 2.75", 5.02", and 5.34"
I imagine the 5.0" would work in both "longer" spots, since my head is the same thickness in both.
The 5" will easily clear under the rocker plate of the 5/8 shaft, paired rockers. I est 0.12" clearance. (checked this morning).
My heads are milled to 60cc, so your clearance may vary (including what thickness head gasket you use).
