HRL,
After reading a different post in another forum, I think I now understand your 'lesson'! If I pulled #1 to the BB or timing mark and was able to get #6 intake and exhaust to alternately move as I rocked the crank slightly back and slightly forward, this would be proof of TDC on #1, no need to check any further...right!
I think I missed this concept in your previous post, if this is indeed the right concept!
If this correct or do I need to call in the grave diggers & shovels?
