I used "two" of the QuickTime plates. On the block side I used an unmodified plate while on the bell housing side plate I drew an outline of the housing flange interface and water-jet cut the interior away. To simplify later tear downs, using an empty block for alignment and solidly bolting the plate assembly to the flange, I tig welded the two together by tacking around the interior of the cut out plate. Proper spacing was achieved while limiting the overall weight.
