check the firing order and make sure you don't have the wire for 5 and 7 swapped .

if you have compression in all cylinders then you should not have any valves stuck open but just for grins you can pull the valve covers and turn the engine over by hand , go thru each valves opening and closing cycle , if you have a valve stuck open it will show up as a very large amount of lash when that cylinder is on the base of the cam lobe .
