Hydraulic lifters on a '6 so the top end should be quiet - the clearances can't be out, unlike a conventional shimmed setup.
Could be a tired / dead lifter, or it could be that you've some dinked valves from someone making a mess of the cambelt install or from a badly repaired post belt snap engine. It's unfortunately a well known problem with GTi-6 engines thanks to the lack of piston-valve clearance, the timing hole slipping on the crank pulley and the engine having a habit of prematurely snapping belts.... do a search for "tapper" and you'll find plenty.
Cam timing can easily be a little out and it run OK for much of the rev range - they're very sensitive to cam timing.
