Yes, you need to make sure you adjust at the correct TDC, as the engine rotates, check the piston location with a pencil or wooden stick in the plug hole. As the piston comes to top on one pass, the one valve will be closing as the other one is just starting to open, as you come up to the other{correct} top dead center, both valves will be fully closed.
