This is a recent email from Debbie at ARP:
Hi Mr. Turner, I got your samples today. The rod bolt part # is 208-6401 (8pk w/nuts).
The exhaust studs are # 400-8024 (10pk w/nuts & washers) These are stainless steel
with studs and stainless 12pt nuts. They have a nut starter end so, they will be a 1/4
longer than yours. As for the head bolts, they are 11mm with a 1.5 thread pitch. We
dont make any 11mm bolts this long. If you would measure the recess in your block,
the thread length on my studs are 1 inch long, then add the height of your cylinder head,
we'll add 3/4 inch for the nut & washer and get back to me so I can get you a part number. Thank You, Debbie
Im trying to get the head bolt part of it squared away but it doesnt seem like she will be able to help. I checked today and the short head bolts have room for a longer bolt but the 2 (center) longer head bolts dont have any extra room for clearance because of the cam. These were the most important bolts to me so im gonna try my best to get some so i will keep you informed and will post pictures of the other fasteners when i get them. Thought i would share because i know a few others would be interested.

Hi Rob, I have a stud 6.35" long part # ATP6.350-1LUB for $10.74 each. And, I have a
7.25" part# ATP7.250-1LUB for $11.33 each. Both of these studs are under cut(reduced
in the shank area). They are the closest that I can find in the lengths that you gave me.
These should work fine i just placed an order for all of the stuff so i will let you know if they dont work by chance. Otherwise this is what you need:
QTY 8 6.35" # ATP6.350-1LUB
QTY 2 7.25" # ATP7.250-1LUB
*then proper nuts for the head bolts (if they are studs)
QTY 1 # is 208-6401 (8pk w/nuts)
QTY 1 # 400-8024 (10pk w/nuts & wash)
