    Never attribute to malice that which is adequately explained by stupidity.

    Terrible luck, I hope you're able to get your engines sorted out.

    From what I could find, this problem only seems to effect pre- VVT/VCT Hemi's (2008 and older). I could very well be wrong, but I couldn't find anything to do with dropped valve seats for 2009+ Hemi's.

    This thread is the longest running thread I could find on the issue:

    Hi, so what is situation now? Looking at the American forums it would seem that a number of hemis dropped valve seats. Could it be a specification and manufacture defect? Seems to me that way.

    The 4.7 and 4.7HO had exactly the same problem.

    Somebody on an overseas forum mentioned heads made in Mexico.

    Maybe they were Tequila Monday versions.

    Well now, if this is true, then I will stick with the V6 that I have.
