Thinking outside the box
It may not be all that hard to do, but how needed is a head like that on there products today. IF Mopar had a car to complete with the Corvette while useing the HEMI engine only and not the V-10 Viper engine, it may very well be a different story.
Believe me Bill, when I'm out there on the back roads in the summer time, the Chevy boy's are screaming like stuck pigs for any advantage they can muster up and site every bennifit the Chrysler engine has starting with the heads.
