New Engine won't turn over!! Help

My "book" says put the timing set on with marks closest to each other or I guess you could say 6 & 12 then line up the distrib. gear at the front corner of the engine.ect ect ... Is it wrong????
Not that the book is wrong but that old school was different setups for the differnt mfgrs. Like others have said, todays aftermarket parts might have any markings. The very best route is common sense. If the #1 piston is at the top, as the crank turns clock wise the cam should turn from level toward opening the #1 exhaust valve.
Today we have dual overhead cams and 3 or more marks to line up to various points instead of each other, and with a rubber belt no less. Get that wrong and break some stuff .
