I cannot see a 'rotor phasing problem'. If the phasing is wrong, the spark goes to the WRONG cyl. The OP says the engine has a great idle & great throttle response. You would not expect that if 8 cyls were getting spark at the wrong time....
Looking at the phasing pics of both dists in post #30, I do not see much difference, given the method used to measure the difference. The rotor tip has a considerable amount of rotational movement, relative to the pick up generating the spark. It moves with the centri weights & with vac adv.
