These bolts arent ARP. Like I say I never had any issues with torque settings. At this point, its too late. I dont plan to take the engine out of the car now that its running, take it apart, replace the bolts and hone the block if needed. I had no torque problems during assembly, the bolts did get cycled 3x's or more.I will replace the bolts at a later date during a routine freshening....I hope...
