will my car pass smog if i put my gt40 heads on? i got smog coming up in 2 months so should i wait? the heads on there now the springs have crapped out because of my e-cam and my 1.7rr. so they may not pass either what to do guys help me out.

the heads will pass emissions and you shouldnt need an exempt order for them. the cam and rockers should be fine as well.

just pay them to pass

youll prolly have to have the engine running at it best or it prolly wont pass, make sure your have a healty conserative tune...9-10* timming, new o'2s sensors, clean the maf,it will be close but youll prolly pass for sure

alright guys i'm gonna do it. you don't think i should slap the stock roller rockers on for good mmeasure?

I passed emmisions with a efi--->Carb swap, GT40P heads, X303 cam, and no cats surely you can do it
