I'm really sorry to say this Geoff, and other members may well disagree, but your experience is what can happen with replacement engines. The fact that the heads were skimmed is also a warning sign. It was either done unnecessarily or because the originals had warped, and the latter case indicates that the engine has not had a good life.

On the positive side "a bit of mayo in the oil filler cap" may be the result of condensation due to lack of use. Could this be the case?

Coolant stains below the water pump were, in my case, the result of drainage from the 'V' due to leaking plastic component 'O' ring seals. Have you checked your engine for this?

However, a 500 ml loss over 100 miles is not insignificant. Are you overfilling the expansion tank? You should be able to see the 'max' marker within the tank. I don't see any justification for removing the cylinder heads.
