What exactly did you do to check the studs?
What torque did you use to check?
Just because you don't find barrel nuts under the valve covers doesn't mean that the studs aren't pulling out of the case.
Unless you re-check the torque, it's still a possibility.
Aside from using higher octane gas, I would also check the curve on the distributor.
With a timing light (Stroboscope), what degree/range on the pulley do you see at 5-6K RPM?
Happy NY
