I heard that in 2010 they had used the R/T heads by accident and some snuck out with the better heads. I found this ad for a 2010 engine if someone is looking.
Um, I know they went to the "Eagle Heads" in '09 and HP jumped from 340 to 370 or so, at least on my Police Charger. My 2010 screams! That's sounds like a nice price.
