HELP with Ignition

[madman213]

my stang needs spark plugs. I was thinking to make a few performance upgrades to the ignition since i will be replacing the plugs any way. Here is what i was thinking :

NGK Iridium Sparkplug
Livewire sparkplug wires
Screamin' demoncoil packs
Steeda timing adjuster

Should I see any decent gains in HP and MPG? Or am I wasting my $$$. Any other suggestions for the parts mentioned?

You wont see much. But its a good upgrade to have if you need the added ignition power for blower/nitrous. Let me know how the coil packs work out for you.
