HelloCustomerand welcome to justanswer.com,
Here is a link showing the timing marks for the belt. click here
there should be slight pressure on the intake side of the valve.
With both cams at the up position-look for a line up hole in each cam. It is recommended that you installed two punches in these holes in order to hold the cams in place. It almost inpossible line up the belt correctly with out doing this.
Let me know if you need any other help.
