Ray, I feel you may be asking the wrong question, a comparison of road speeds isn't likely to help you much.
If your engine isn't running cleanly at speed the first thing I'd do is check your ignition points and gap them, clean or replace as necessary. Hitting valve bounce is generally quite noticeable and I don't think you'd mistake it.
