[Healeys] High speed miss - more info

The rebuilt fuel pump would be my first point of attention. Try 
measuring the delivery of fuel in liters /min and the fuel pressure. The 
fuel pressure should generally be around 3-4 psi, fuel delivery should 
be at least 0,5 litre per minute at the normal pressure.
Another point to check is your dwell angle.
