You'll get lots of opinions and I'm sure that everyone has had good luck with their combinations.
Personally I ran a Weiand Stealth (no egr) with a Holley 850 double pumper and a 2" spacer. I had excellent results with this combination.
It fed 500 horsepower with no problems.
I will say this though...............if you're not making any other changes to your mill, it's unlikely that you'll get any kind of significant performance increases.
I switched from an Edelbrock Torker I (real crappy intake) to the Weiand without changing anything else, and gained nothing.
