hey all pretty simple question but im too dumb to know the answer

now when u put your motor to "top dead centre" and put the head back on, there are marks on the cam cover that you line up to marks on the cam gears

now my question, there are 2 marks about 1-1.5 cm away from each other on the inlet cam gear, i just want to know which 1 i line up with the mark on the cam cover

thanks, brendan :2thumbs:
