I hope you accounted for striction when you tried to retorque, especially after that much time. It'll make a bolt read 140ft lbs of torque when it was only ever torqued to 100ft lbs.... . A bolt which has been through a couple heat cycles will stick and need to be backed out 1/8 to 1/4 turn before being torqued further.

For those not in the know: Striction = Static friction and is VERY important to pay attention to when dealing with fasteners. Fasteners need to go in good and smooth. If you encounter striction while tightening a bolt you'll feel it stuttering or popping... This is B A D and tells you that the fastener isn't lubricated well enough and is going to torque below what you read on the wrench.

As I said, drive like a sane person. If you don't know any whom you can mimic, try cruising between 2K and 3K and shift by 4500 to 5000RPM. Essentially drive casually but not like my 90 year old neighbor and not like a teenage human male. There's nothing written in stone on the matter and it's less finicky than cutting new rings.
