Ditto on wiggling the rockers. If you're spinning the pushrod you should begin to feel a light drag when trying to spin it, not necessarily so tight it won't spin.
When you adjusted them did you make sure you were at #1 TDC compression and not on the exhaust stroke? You can verify #1 TDCC because #6 will be in overlap. When you went to the second set of valves did you rotate the engine one full turn before starting?
