Lifter Replacement??

Are you sure its a lifter??..when a lifter is bad the noise usually comes and goes.it not consistent...

It is very consistant, a little quieter with temp, but not too much. Its not a death noise, but just a general consistant click heard at all RPM's, louder at 950 RPM than 750 RPM for example. Can't think of what else it would be.
