Thanks for your ideas on this. I realized after I posted the question....duh why don't I just ask the converter manufacturer?
So I called Dynamic and they indicated the gap between the flex plate and the converter should be between 1/8" and 3/16". This is with the converter seated. Note the flex plate is bolted to the crank flange, but the converter is a slip fit into the trans. When I said "shimming" I meant adding a washer between the flex plate and the lug on the converter. This effectively seats the converter deeper into the transmission. If the gap is too big, and you take up all that slack with no shimming, the converter may not seat far enough in the trans = damage.
The bottom line is that shimming is OK, according to Dynamic (I checked with Hughes as well). Use hardened washers and mike them all so they are equal thickness. So now I am off to double check my measurement to confirm the existing gap is indeed > 3/16".
