Bad to do cams without headers?

So if i'm planning on going FI in the future (not anytime soon) and i build up for it, say plenum, cats, clutch, flywheel, is it bad to do cams without headers if they would be replaced by intake manifolds anyway?

With a mild street grind like JWT S1 or Nismos, no you don't need headers, thoug they woudln't hurt.

You don't "need" headers for any CAM upgrade, Its just with more radical profiles you will gain more up top with a good scavenging set of headers on an NA setup..
