I am curious how much torque you put on those new rods K-star. I have the same ARP bolts in my rods. I called ARP and they recommended 62lb/ft with moly lube, which I used. Mine came torqued in the rods and were torqued another two times between the engine rebuild and my machinist checking them at that time. If the trend is that stretch gets easier after a few cycles, I feel better. 80-90 lb/ft is a big difference over 62....makes me a tad nervous.
