Which header is recommended for a stock 5.0 EFI? Someday I might want to add a supercharger, so I probably want room to grow.

Factory is 1-1/2"

Suggested modification is to go with a 1-5/8"

Most after market's are 1-5/8", I'm using MAC Shorties per FFR's Recomendation.

definately 1-5/8" and Macs do seem to fit the best.

Go with a single flange style, like the Ford Motorsport or even the Flowtech. I have heard MAC's warp and don't fit well at all. 1-5/8 is the way to go. I have the Flowtech's on mine, and just picked up a set of FMS 1-5/8 unequal length shorties at a swap meet for $200, ceramic coated and brand new in the box.

Get the Stage 8 locking header bolts too. Once they are on, you don't have to re-tighten them.

FYI, that's not a typical price for those.

figure $250-290
