SpeedMaster Heads for a 5.9 Magnum
The speed master aluminum head just needs a good valve job ..though could benefit from a 2.05 or bigger intake valve to gain a better venturi bowl shape. Exh port work required is minimal.
I'd do a little chamber shaping at the far side and light short turn chamber side pathing is all.
