1996 Plymouth Voyager Put New Heads on and now this........

[JDiMassi]

put a set of rebuilt heads on my 3.0 96 voyager and they tap like crazy i mean its terrible have had them on there for 4000 miles already and its driving me nuts i replaced the heads crossover tube and water pump due to overheating issues and it didnt even tap with the old heads now i put the new ones on and im tapping any one have an easy fix to this ???

its kind of intermittent but 90% it taps and the heads were rebuilt units from a cylinder head shop i ordered them online and i cant really hold them responsible but its more of an annoyance id like to fix

I'd say that the heads were NOT rebuilt or not done correctly. The clicking is the lifters.
