If you were right, unfortunately your experience has no relevance to the OP's question. Did you read the Tech section from ARP? ARP does not torque past yield! They do not allow plastic deformation! After .0005 of plastic deformation they say throw the fastener away. Read torkflight's post. It includes the best way to check the stretch with the tapered holes in each end of the bolt, already there from ARP. Here is real world experience with real results. We are not buying OEM bolts to put in our HP Mopars, we are using better fasteners. Designed and tested by Engineers to outperform OEM. I see you are one of those guys who always has to be "right", whether you are or not.
