I have found this not to be the case on rods that come with ARP bolts. Some are the same, some 2-3-6 thousands off using the same tool in the article.

Possibly a NEW package of un used bolts from ARP might show different. Bit I do not know.

That article does not seem to be correct if they claim all bolts are the same from the start.
