Running Lean

So my headers cracked and now I got new ones, when I was taking the headers off I noticed the inside was white, so then I looked at the valves and noticed they were also white, something that usually means that the engine is running lean, any ideas?

Mods: K&N, Samco y-pipe, Supersprint Headers, Supersprint Cat-less up-pipe, Supersprint 2.5" Cat-less turbo-back. Any and all suggestions welcome.

Thanx in advance...

No, that means you're burning coolant. This is a 98 isn't it?

It's a 2003

Sorry I was under the impression that when u use the term turbo-back and y-pipe that it meant WRX...

You never know around here....

It may well be lean, but that is usually accompanied by knock and hesitation. Have someone follow you a couple times- if you get white smoke, even puffs, it's definitely coolant.
