the build up looks fantastic!!! with the rear drum brakes, i'd just leave them there and see how the go, remember that installing a hydraulic handbrake is not only illegal in most Aussie states its also a pain in the ***.
One question that cropped up was; did you baffle the sump at all? I thought of this after you mentioned the motors poor oil history...cos the new motor wont be going so great if it can get an oil through its guts. But then again as you said its only a daily driver and all this depends on how wild you like to drive
