That engine does not have lifters. The cam has rockers, which are in direct contact with the valve. Lifters are used to take up valve lash in larger engines where adjustments are redundant or not easily performed.
The noise is kinda hard to hear over the engine itself. I would invest in an engine stethoscope to help narrow down the location of the noise. If it is lower than the head, but not quite in the gearcase, then you may have piston slap, or a wrist pin issue. I assume you made triple sure the circlips were properly seated when you installed the piston?
