I buy studs separately from B&B however, the lengths are the same no matter where they come from.
For stock type heads, the longer outside studs are 5 3/4 inches long and the inner shorter studs are 5 inches long. That is with at least 1 inch of coarse threaded end going into the block.

If they are for the A460 heads do want to sell them??? I need a set very badly!

You can't use them. That part # is for the older A429, Kaase P51's, and newer FRPP SCJ's. Won't be right for A460 heads, I'm in the same boat and need a set.

Its gotta be the wrong part number on the box because those are the lengths for A460 heads according to what arp told Rich. We have a set of 6.550 and 5.550 and they are ~.500" too short but they were in a box labeled as A460 studs.

I believe correct lengths are 7.625 and 6.120" for the A heads.

Hmm, maybe so. I went and checked the box I got to use on my d0ves and its the same part number listed here. Looking at ARP's site, they say a 255-4304 is needed for A, B, and C-460 heads.

We need some really badly and it hurts my butthole a little thinking about the fact that ARP discontinued the ten bolt set that was about $80 cheaper and now sells the eighteen bolt set under the part number.

ARP 255-4304 is the 10 bolt A460 12 point nut stud kit.

TFS-54504304A is the TFS kit for the additional fastners for the 18 bolt heads.
