Default Do heads affect emissions?

If I get TEA or Patriot Heads will I have trouble passing emissions?

no, your cam choice will have a greater effect then heads.

tea 5.3's and tr224 114 have passed cali smog so it'll pass anywhere.

lol, you are correct . im gonna swap in a 224 112 and i'll swap the exhuast out if i have to for the visual.

the tea 5.3 setup with 224 114 cam and bolt ons should clear the 400rwhp mark on an m6.
