Double check for exhaust leak. They can sound real close to an engine tick.

Do the plugs for that cylinder and the adjacent one look normal?

Warm the motor and pull the belts. See if the noise goes away. Had a PS pump that started making a knocking noise right after I had installed a new crate motor. Was really happy when the knocking noise stopped with no belts installed.
