2 easy timing questions

I got tweo stupid questions but i cant seem to find the answers. First im trying to turn the engine over a bit to get it at tdc on #1 so the damper timing mark will line up with the timing mark on the front oil cover behind the water pum,p. question # 1, how cna i turn the enigne over buy hand, i tried a big wrench on the bolt that hold the damper down but no luck. and also theres like 5 notches on the oil cover timing thingy(technical term) what one is 0 degree timing? Trying to set my base timing on this motor and maybe start it up tormrmow thanks guys!!

You may have to take the plugs out to turn if over from the crank bolt. You can "bump" it with the starter to get it close. The deepest V is TDC. About 3/4 of the way down.

Yep, bottom of the "Big V" on the tab is 0* (TDC).

An easy way to turn the engine over is to leave the belt on and turn the engine over by the big nut in the middle of the alternator pulley. That pulley is 4 or 5 times smaller than the crank pulley which means you're getting 4X-5X the leverage on it versus trying to turn the crank pulley directly. You will need to hold some extra tension on the belt, however, to keep the belt from slipping while you do this.
