All headers that I have seen say they fit engines with no manifold intake. I am not sure if my engine fits these headers can anyone help find the right ones? http://www.truckperformance.com/prod...ber_JBA1842-3/

 

I have a 97 blazer 4.3l 4wd

 

GOD!!! WTF. Anyway, please try to format your links so they aren't a FREAKIN' mile long!!!
Anyway, I don't know the ramifications of removing the air injection. To use those headers (like I have already stated before the last time someone linked to them), you would need to remove the air injection system entirely.

 

Here's one for you:
Edlebrock T.E.S. - SummitRacing.com

Although it doesn't say anything about Air Injection or EGR, but you could always email Edlebrock. That would probably be the best place to get an answer from... Woooh, Deja-vu... I distinctly remember saying that one...!

 

I saw those and its for the cpi engine.

 

I would contact Edlebrock, because these are being used in S10's all over the place, but I don't know what they do with the air injection system. Just because Summits site says that its CPI only means jack crap. Do some digging (ie. contact the manufacturer).

 

Another place is Hedman. They make headers for our trucks as well.
