Default EJ257 cam sprocket/timing question

Hello,
Iím nearing the end of my EJ257 build (first time subie owner).
I had a valve job done and put new cams in. The cams really only appeared to go in one way, rotationally and they feel real smooth.
I torqued the cam sprockets but canít find my cam lock tool. Iíve read about not spinning them because the valves stems could bend but Iím wondering if thatís just directionally or speaking in terms of both the intake and exhaust cams together. Iím not spinning them enough to feel any friction so I hope Iím still good.

Iím currently about to put on my pulleys and get ready to put the belt on but just wanted to make sure I can rotate these camshafts/ sprockets to get all the timing marks lined up.

Remember that you spin the intake came counter clockwise and the exh clockwise. The cams are labeled should say rex or lex on the exhaust cams and L-in or r-in on the others

So I installed the belt and got everything lined up rotating the LH cams properly to line up the marks. Gave the crank several turns but realized I didnít take the tensioner pin out. Now all the belt lines are lined up but the camshaft pulleys arenít seeming to line up with them.
Did I screw this up?
