Default Breaking up a little after pass...

Made 2 passes last night and after the second my car was kind of breaking up above 3000 RPM. It was like a miss. I pulled the plugs, all looked good. A/F was in the 11.0 range through my passes with no detonation. After the engine cooled down it seemed to get better, I'm going to pull the valve covers this week to fix a couple leaks so I'll check the valve springs then. The car goes pretty rich when I let off after a pass, I'm almost wondering if its fouling plugs? I'm going to throw another set in anyway, even though these have maybe a few hundred miles on them.

Thoughts?

Went out and drove it tonight, seems OK. I'm probably just paranoid, but it was for sure breaking up bad last night. Sounded like it was on a 2 step.

10.14 at 139.36, 1.63 60'. Good MPH, just that the car leaves like a 12 second car.
