The “Magnum R/T” head is a aftermarket MoPar Performance head.
All other Magnum engines have regular heads no matter what vehicle they came in or what trim level they were badges with. That means any Chrysler production vehicle that was designated a “R/T” DID NOT COME WITH R/T heads, ever!
Bingo, Bulls Eye, 100% correct-O-mundo!!!!!!!
The MoPar R/T head was ONLY AVAILABLE through MoPar Performance.
