You should have 2 dots on the cams one on each. and on the crank there is a locking lug for the cog the lug should be facing up in the middle of the engine. put in middle and turn 2 cogs to the right then it is in tdc. for twin cam's, here is some pic's to help you.

First pull the timing belt tensioner then slip the belt off the cam gears. You then need to find TDC (Top dead center). 3 ways to find TDC 1) There are marks on the crank pulley align them for TDC. 2) Remove timing cover and use crank gear mark seen in link below 3) Put the dip stick in cylinder 1 and turn engine until dip stick stops going up. After finding TDC align cam gear marks seen in link below. Now make sure both cam and crank stay in position and slip timing belt back on (you can move the cam gear to get the belt on but make sure the marks are aligned after the belt is on). Last tighten the belt tensioner, I usually use my finger or an extension to get some more tension on the belt. You might have to remove engine mount bracket makes life much easier as the front cover section is TIGHT !!!. Turn engine a few times to make sure you have compression and engine turns without getting stuck. See link below good luck.
