Ok here it is, I have a B20 block with my B16 head and I got the AEM adjustable cam gears now to match up the lines on the cam gear is simple but can someone tell me if the line with the circle around it goes on top or on bottom because there are 3 lines on each cam gear and if you match up all the single lines across there is still one line left that is either up or down thank you
