Help me add 100 hp to a magnum 5.9 on a super tight budget

I like being a copy cat sometimes…

Stock 5.9, M1 single plane, 750 cfm carb (Holley preferred) 1-3/4 headers, Comp Cams copy cat 380/360 crate engine cam that has more lift.
Add minor head work so the valve retainers clear the head. Give it a milling for a .5 increase in compression.

Change the stall on the converter to match the 4.30 gears and go clean his clock with an extra 100 shot of N02. You’ll clear 500 hp.
