Did everyone miss that he has 20w50 oil in it? I run that in my Harley-Davidsons, fer cryin' out loud. Drain that sludge out, put some 10W30 back in it and try it again. The only time I'd use 20/50 in anything would be if it calls for it - this doesn't - or if I have clearances I can measure with a carpenter's measuring tape. Since the engine is brand new (I know, a fresh rebuild), I suspect it's not flowing the thick oil properly at temperature.
