Could this cause any cam gear alignment issues?
Usually it helps the alignment instead of hurts it.
I think some of these cams are made and assembled by sub-contractors. Most are exactly right in the spacing of the timing gear, fuel lobe and valve lobes...they are in the proper position, but the whole camshaft is shifted one way or another by the "workman" who sets the collar. If a cam lobe is not hitting a tappet correctly the chances are the timing gear is off by the same amount.
