High rpm missing is usually an ignition problem . It is unlikely to be a timing problem. Start off by installing new spark plugs and if that doesn't help then replace the distributor cap and rotor and then plug wires if necessary. It could be a problem with your "electronic ignition" or your coil could be on the fritz but they are less likely causes.
If your engine is using a capacitive ignition and your rotor has a carbon conducter in it they will burn out. Particularly with multispark. But burned rotor conductor is evident at all RPMs.
There`s a post in my thread (TechnicaL Questions and Suggestions) on converting the rotors that are only available in resistor types. Such is the case with Marelliplex rotors.
The "High Voltage" resistor type coil & plug wires have a shorter life with and particularly High Energy ignition systems

I shared a version of the following embarrassing story with Marc T. earlier and thought it would be best shared with the group:
