Mopar Performance magnum R/T heads

Those are excellent heads.
I has a set on an enginemasters 318 motor i ran in a 3400 pound car. Kinda street strip deal with only 4.10 gears, small tube headers and a 231/238 hydralic cam
Went 11.60’s on pump gas( 10.4 compression) with a flat hood.
They make excellent power
