Yeah most definitely adjust the CCT a smidge. Loosen the two outer 8mm bolts on the CCT enough so it pushes itself out maybe 2mm. Then retighten (lightly) the outer two evenly (like one turn on the top, and then one turn on the bottom). The torque values on them is like 8 ft/lbs so you don't have to go buck wild. Fire it up. If it's kind of tough to start then you need to loosen it a bit.
If this is the case, take the 10mm bolt (from the center of the CCT) off and stick a flat blade screwdriver in. It will allow you to turn one way (clockwise I believe). This removes some of the torque from the CCT. Start it up again and see how it is. You should have a SLIGHT ticking noise and that's it. If you back the center screw all the way off and your valvetrain is loud again, then you have to loosen the whole CCT assembly again. It's all fine adjustments so you don't have to go buck wild with loosening the CCT assembly or backing the shaft off. Good luck
