Camshaft timing alignment?

I'm looking to get the camshaft on position mark upward. For I can continue the alignment.

Help! Timing guides - engine won't turn over by hand

I need your help as I am stumped.

Changed the timing guides, went to turn over the engine by hand and it won't make even make 1 full revolution (need 2). Going clockwise it gets stuck around 7 O'clock; going counter-clockwise it gets stuck around 8 O'clock. So there is something between 7-8 O'clock that is preventing the engine to turn over (has to be valves?). Engine ran fine beforehand, so it can't be a bent valve.

When I originally locked the flywheel, I was 180 degrees out of time (letters on cams were facing down). Chain tensioner was removed. After asking the forum members, it was confirmed I was out of time, so I installed the chain tensioner tool and turned the engine over so the letters on cams were facing up (1 full revolution). I am afraid in the process I've messed up the timing somewhere.

If I take off the cams, will I be able to turn the engine without interference from valves? My plan is to:

1) Take off the cams
2) Turn the engine over and see if I can make full revolution (2-4 times, just to be sure)
3) Set crank at cylinder #1 TDC and lock flywheel
4) Reinstall the cams (letters facing up, squared and locked by blocks)
5) Pray really hard.
6) Turn the engine over and check if there is still an issues around 7-8 O'clock position
