How many of you are having the "click, click" no starter spin when hot are also running an aluminum flywheel? Have you tried putting it in gear and nudge the engine rotation a couple of degrees then try again. Chances are good you will need to shim your starter to compensate for the increased expansion of aluminum. The bendix drive is set up so the starter will not grind the flywheel by spinning (energizing) the starter motor till right before gear engagement. If an aluminum flywheel has expanded to the point of gear contact before the set travel has been met, then no energizing of starter, hence, "click, click".
