I was reading the summit catalog and came across a section on the LS6 heads and it stated, that it will only pass emissions with the ZO6. Can someone shine some light on this and tell me why is that?

 

PFFF. Dont know what they are talking about. We will see at the end of this mounth.

 

It was an old catalog that i was reading. The one with cobra on it. Okay let me restate my ?. Is it true that LS6 heads are emissions friendly only on the ZO6 Corvette? If yes why?

 

Hey goober
Reason why I ask is because I want to run the LS6 heads, cam, intake because of the Ca smog laws, and read that this combo makes a decent hp, tq. Sorry didnt read your post close enough. Dont mind me Im at work and its 7:20 in the morning

 

TTT please

 

Hi Folks,
The LS6 heads are emission legal on the Z06 because that is the package Chevy submitted for emissions. Technically you can't change the headers, etc because it is different then the package certified for emissions. That is way they say for off-road use only. The same thing here, you probably will pass the emission test with the heads. I have them with no DTC but the LT headers are different story.

U will pass CA emmisions.

 

Thanks Bill, and goober for the feedback.
