Probably zero (they may actually cancel each other out), or certainly less than 10.

The ported TB and descreening the MAF are worth while and will give you a bit more HP.

A good cat back exhaust and cold air intake will do more for you.

178 thermostat? Does nothing for horsepower. Just lets the water flow through the engine at 178 degrees which helps your engine run cooler.
ported tb? Will only help if you have bigger heads to handle the increased air/fuel.
MSD wires? Just gives a hotter spark which helps burn fuel more efficiently.
iridium plugs? Hotter spark/longer life.
descreening maf?[/QUOTE] Lets more dirt into the system.

You should go get a good dyno tune and maybe some LT's.

No, No, No, No, No, and No, provided you don't have bad plugs.

No more hp, but iridium plugs are a good investment if you need plugs...........
