Need some pro advise....

Did you torque the bolts with an extension? An extension, especially a long or smaller one, will lower the torque to the bolt.

I know online somewhere there is a formula to calculate this torque loss when tightening fasteners.

I also put a drop of oil under the head of the bolt. Something I've been doing since I started building engines.

After that I think I'd replace those bolts. Are you sure on that spec? When I did mine last year, I could have sworn it was over 200 ft/lbs.
