timing belt position

i am putting in cams and springs, and i was just wondering how to put my timing belt back in the right position. i have heard that if you dont get it right you can bend your valves, and i dont want to do this. also any other pointers on changing cams and spring would help, i have found info on a few sites but im still a little scared of messing up.

look on the cams and pulley there are marks on them. depending on ur engine the marks wil be different. ull just have to line those up. this link might help
