Are you referring to more than one noisy lifter? Have you verified oil pressure? What weight oil are you using?

Try a fresh oil change and substitute a quart of Marvel Mystery oil for one of the quarts of oil. If that doesn't work, you just have to replace the lifter, assuming it's not something else like a rocker or valve spring problem.
