Bearings already changed. No marks anywhere on the cams except those pictured, NONE!

I just pulled the stock cams out of my '06, they did not have dots. They had lines, and not the line the OP shows in his photos. Should be one distinct line on each cam each toothed gear.

Well I was wrong.. Those are stock cams and the marks you are lookin' at are correct.
Here is a set of 02s out of my 02 RKC The marks on the ends correspond with marks on the teeth and they are in the right position for the missing tooth on the outer cam gear spline..

I would install them with the squiggly lines pointing at each other in the same plane.
EDIT: As shown above in the bwoltz post
Then slip the sprockets on and see if the dots on the sprockets line up as shown in one of the attached photos. If the sprocket dots line as shown (picture shows dots, not squiggly lines) then the dots on the cam sprockets should line up as shown in the other picture which would be TDC on the rear cylinder which is the #1 cylinder. I would try that and see how things line up.

Yup, those were the lines I was talking about.

Should of taken a picture when you were in the disassembly stage... But IMO the marks you are point to are the ones you line up.
