different resistance does not mean nothing.
different vendors build different preamps but pin functions are still the same, that's why same rom version can handle them.
I will not uncover the points where 'incompatibility' comes in, there are more than one.
But there are ways to overcome them most of the cases.

Did you ever succeeded to use head donor from completely identical drives but different resistance pinout ?

probably, i did not bother with the pinout resistances, that's completely out of interest.
What's more important is preamp vendor and type. Donor MHAs normally clicking in the patient were reading fine after some magic.
