It was luck more than judgement, I guessed the difference between turbo 962 and 910 n/a fuel delivery related to plunger/barrel size - this turned out to be correct.

Visually the fluted plunger from worn DV sat lower in holder, perhaps by 2/3mm - hard to tell exactly, the fluted tail fit inside convinced me it was worth a chance, if the tail cannot maintain a vertical path it may seat at varying angles with each stroke.

As mentioned above, I have had to dial everything back as too much fuel being delivered, this suggests the DV's were allowing fuel to bypass the seat.
