Easiest way to set TDC:
Remove all timing belt/pullies, and make sure to remove the spark plugs (avoids creating compression). Put the crank pulley on the crank (by crank pulley I mean the one for the accessory drive belt), and you'll see a tiny notch in it. Line up this tiny notch with an arrow on the block. Line up each cam with the cam alignment tool or something similar so that way the ends of the cams on the driver's side line up. Install the belt first on the crank, then tightly pull it up to the front cam, then over to the rear cam, then over the tensioner. Set the tension so there is about 1/4" play up and down on the belt between the cams and tighten the tensioner.
