The differences are many but I can see no reason why a later model engine could not be used if they fit inside the cowls and on the mount. I know there was a change in engine diameter but I cannot remember which diameter is first - I think it was the larger one though and I know of at least four engine mount systems but that does not mean there were not others. Standardization is not a British trait.
A number of the later versions had torque meters but that is only a nose case change and if it was left on most people would not know the difference anyway. Most postwar engines had rear exhausts and that is only baffle changes from memory
The attached manual covers one set of post war engines, several mounts, several exhausts, with and without torque meters. The watermark is to stop unscrupulous scum selling copies of the manual.
