Yes, the tip style does matter and it seemed like the measuring surface in the bolt head was not very uniform on the Molnar 2000 bolts. I gave up and just torque them using torque to yield method Molnar suggested. Rods are still in the block 5 years later. Callies included an instruction card with torque suggested torque method, torque to 25lbft then to 92. I just question that as that is not my method of torquing a bolt and the final spec seems very high for that size of bolt, but then again i have never dealt with L19 bolts. Thanks for the info. I might check stretch on all them if the numbers look trustworthy.
