e.f.i manifolds for 300 6cyl

i have benn reading some of you guys are saying that the exauhst manifold off the e.f.i 300 6cyl. is a good replacement for a performance upgrade on the old school 300. is it worth going to the local picknpull yard and getting one at there half price sale this weekend? will it be a noticeable upgrade?

I've heard of quite a few people doing it. It's a good way to get you true duals. If I recall correctly there was a small HP increase, but it wasn't too much.
 
They flow better than the stock log manifold, but I doubt you'd notice anything in your assmeter w/o buying a new intake and getting a bigger carb on it.

I don't think the factory exhaust manifold works with the performance intakes, so if you plan on making that swap in the future, go ahead and pick up the efi manifolds.
