Need advice 360 timing chain cam/crank slightly off

I would read a book before listening to Uncle Tony. :lol: Lining the cam at 6 and the crank dots at 12 just makes the dot to dot lineup easier . to do both at 12 id use a straight edge i agree it makes no difference. All this info about dot to dot lineup should be in a shop manual. This is how a pro mechanic would replace a timing set in the 70s or 80s. they werent degreeing cams back then well, maybe in a performance shop they were. They replaced timing sets because the nylon teeth gears would wear out.
