Mopar Performance magnum R/T heads
Those “Magnum R/T” heads are MoPar aftermarket heads and NOT stock OE heads ever. R/T Vehicles had regular Magnum heads. Never R/T heads.
I forget what they flow over the OE regular production Magnum head but an improvement they were.
Ryan J @ shady dell speed shop knows how to port these into some real performance/race monsters.
