MBN C15 valve adjustment

I replaced my middle Jake brake and updated the 12 bolts that hold them and the rocker shafts. I rotated my engine and pinned it. I see that it's #6 TDC. So I adjust intake, exhaust and the Jake on #6. Then I adjusted intake on #5. Then when I went to adjust exhaust on #4 it is open about a half inch. Can anyone tell me what I'm doing wrong? I am turning the engine ccw if looking at it behind the flywheel. Thanks in advance. First time running an overhead. Thanks in advance

 

All the research I've found says if tdc on #6 is adjust intake on 3,5, and 6. Exhaust on 2,4, and 6. Am I missing something?

 

So yes I did pin it and #6 were both closed. #1 the intake was closed but the exhaust was open so I just assume it's #6 on top dead center. BUT after searching online I seen where someone had the same exact problem as me and he was replied to by saying either a bent rocker arm or the flywheel is not on right. I don't think my rocker is bent so tomorrow I'm going to try doing what you mentioned (the rock roll adjustment). Because if what you're saying is true then I'm not on either tdc. Hence motor pinned and #6 both closed. #1 intake closed exhaust open
