2. I purchased a genuine Porsche crank pulley (# 91110201704 V-BELT PULLEY) and a new flange'd hex bolt (# 99909300502 HEX BOLT).
3. when I checked the new pulley by the same method it was so much better than the original less than 0.3mm wobble (Was at the limit of my measuring set-up).
4. When I installed the new Pulley on the crank with the new Hex bolt and run the engine I could not see/detect any wobble at all it was perfect/true (Unlike the original).
Still a mystery how the original got distorted in the first place. There was a suggestion that the pulley's have been known to distort overtime/45 years. !
Thanks again for the support.

I am amazed it is possible to remove the pulley without removing that engine mount that surrounds the pulley. I just replace my seal behind the pulley, and that required removing the muffler and a lot of other items, and dropping the engine a couple of inches. Glad it worked out for you.
All I can guess is at some point when the engine was moved while out of the car, something somehow bent that pulley, or maybe during the rebuild it was bent. Steel does not spontaneously warp like a piece of wood can.
