Difference between Magnum and non-magnum

As the topic states, what's the difference between a magnum and non magnum engine? If someone could explain what parts are different, and what parts do what that'd be great. Thanks

Cylinder head has different exhaust ports, valves/keeper with 3 grooves, heavier duty valve springs, and a more agressive cam.
(better flow)
The intake manifold is a dual stage aluminum piece, for both high and low rpm power.
(better flow)
The exhaust manifold is actually a short tube header coupled with a high flow cat.
(better flow)
The PCM is more agressively tuned.
(takes advantage of higher octane and better flow)

So with the use of the magnum head, intake, and exhaust header... Premium still wouldnt help unless the ECU is also installed?

No, premium would still help.
