LT1 header questions
 

Hello all. I have a couple of question and I would like to get them cleared up before I buy headers. I wanna go with long tubes and preferably stainless. Is there still any affordable stainless long tubes with A.I.R and EGR hookups? If I decide to get headers with the hook ups and then decide to get rid of the A.I.R and EGR system is there a way to block off the connections on the headers? I know about the block off plates for the engine but what about the headers themselves? Thanks again guys for any input!

The PaceSetters are available with AIR/EGR. Mild steel, but available with cera-metallic coating.

Interesting that they say "emissions" but I don't see any evidence in the photo.

If you buy a 3-piece EGR blockoff plate set, one of the plates is for the connection on the header #8 primary. AIR can be blocked but the specifics will be determined by what type of connection they provide on the headers... internal or external threads, requiring a plug or a cap. Not all header AIR connections match factory. Some require adapters.

Here's a better picture from Summit. It looks like they have the A.I.R. ports and the EGR exhaust tube.

Make sure the emissions tube on the top of the header match the emissions fitting on the car. Good luck, let us know how it turns out.

Ok thanks guys! I'll be getting a pair when I get the money together!

Yeah stainless you'll be paying more. Stainless Works has a good set, so does Kooks.

I used to think Pace Setter's were cheap but that was several years ago. Now that I have a Z28 I'm seeing a lot of guys using them. Searching on the net I see you can get them from plain to coated. When I do go LT headers I won't rule them out by any means.

Yeah they are definitely becoming popular. I need to figure out if you can still pass emissions with the egr and a.i.r codes tuned out.
