'05 Hemi ?'s

buddy had a 300, dropped a seat on one head, had head replaced with a JY head. Next month, he dropped another on the other head! Went back to same JY, bought the other head, slapped it on and sold it. He was pissed because he had bought 3rd party mechanical insurance in it, you know the ones that advertise...they denied him coverage because the problem was not "lubrication related"....read the fine print. I have also heard of peening the seats, basically you take a blunt punch and tap divots around the valve seat so it deforms the head material for more of an interference fit, not just a shrink fit.
