Have access to a brand new set of A1 rod bolts that are the same length and everything as the ARP 2000 bolts in my Eagle BBC rods. They are the AMS55844 material that is like 285,000 psi. Just curious if anyone has used something other than the recommended bolts by the rod manufacturer. Not a big deal to spend 140 on a set of L19s but these are given to me to use if they will work. They are both 1.800 underhead length, 7/16 thread and the shoulder that goes in the cap dowel is the exact same diameter as well. Just looking for input on this.
