Are you referring to the complete set of specifications? Or is it the size of your head? As far as I can recall. The head on the set I bought was 12mm. I believe it was thread number seven. I can tell you that they are only interested in that camshaft series. For the past 8 years, they've only used one type of bolt. I hope this information is useful.
8MM X 1. 25 X 25MM
If it's a LS engine, but you're not sure whether you have a one-bolt or three-bolt cam, go to a chevy parts dealer and he'll tell you.
Because ARP lists the same part number for your engine, they should be compatible.

Tighten them to 25 ft lbs, according to them. They come with assembly lube, so make sure you use it to get a precise torque reading. These bolts are extremely durable.
On my LS3, I used it to replace the cam sprocket. Especially if you're using an aftermarket cam, this is a must-have. We don't want these bolts to come undone! Only lubricate the threads and behind the bolt heads with the lube provided in the package.
If it was possible, I replaced every bolt in all of my vehicles with ARP. Their quality and long-term durability are unrivaled. They can also be used over and over again.
In critical fastener locations, I always use ARP bolts. When doing a cam swap, these are inexpensive insurance.
Many people believe it is excessive, but it will last until the next cam swap.
As expected, there is a bolt. It worked flawlessly.
ARP cam bolts, duh, duh, duh, duh, duh, duh, duh,.
