Does your 6.4 Hemi eat lifters?

This is a little bit of a stretch for tow vehicles but since the Ram's have the 6.4 Hemi option it kinda fits.

I have a Challenger 392 SRT with the 6.4 and it developed a tick at 24K miles (believe it or not, it's been babied). From my research before buying, this engine does not normally suffer from the infamous "Hemi tick" that the 5.7 does.
My tick ended up being one badly worn lifter. While they were in there, they found two more on the opposite bank that we're also worn. Cam was inspected and found to still be fine only because we caught it early. I'm told that sometimes this takes out the cam as well on this eng.
Dodge ended up replacing all 16 lifters under warranty (and had it three weeks because there were 5000 lifters on B/O).

The truck has a very different eng tune but has anyone heard of or had lifter issues with their 6.4?

    Only 5k miles on the wifes new SRT Charger and the main reason we bought a new one (other than it's cool looking and performs like a car 2x it's price) is because our 06 has been for all intents and purposes Bulletproof.
    I don't get on the SRT forums much but from what I have, I don't recall it being a prevalent issue, the "hemi tick" on the newer vehicles
