keep at it and check the important stuff ,the service limit values for the engine parts in the fsm
do not scrape or "clean" the pistons on the sides leave them be the buildup on the sides helps the pist fit better than it would "clean" do not use anything to clean the ring grooves besides compressed air and a very soft non metalic parts cleaning brush
dont polish the top of the pistons you want some carbon up there,get them shiny the carbon will never stick
a good running motor the exhaust valves would be almost white after al,l they are near red hot during hard running
the marvel mystery oil was a waste of money for the purpose of cleaning the engine before you tear it down it can actually do more harm than good on a plain bearing crankshaft
the internal parts that you pull out as long as you dont shovel dirt on them they can be bagged and put back in when you are ready, total waste of time to "clean" most of that stuff exceptions can be clutch basket if it has collected a lot of frictioin material
i repeat the most important part measure everything as per the specs in the fsm
critical things being small end of rods and crank runout piston to wrist pin lots of stuff nreeeds checking
