I would respectfully suggest that you make sure that you adjusted the valves by placing the feeler gauge between the cam and the rocker arm pad. There are those that have mistakenly placed the feeler gauge between the lifter and the top of the valve. Don't ask me how I know.
Also, make sure that the cam lobe is pointed to the sky.
