cant find LT1 headers???
I have been reading around everywhere and I keep seeing people say to get the Hedman 68479 headers but the problem is no one carries them anymore. Does anyone have a part number for a shorty header that will work on a 89 firebird with the LT1 swap plus could they be stainless steel too please

Re: cant find LT1 headers???
all the ones I have found are round port and not the D port though. Will they still work?

Re: cant find LT1 headers???
You may have a hard time finding LT1 swap headers.
Here are the part numbers I had saved from when I did my swap.
They aren't stainless though.
Hedman 68469- long tubes
Hedman 68479- shorties
Hedman 17478- y pipe for shorties
You will have to weld o2 bungs on either option.
After a quick search Jegs appears to have the long tubes.

For Gen2 LT1's its pretty much add a O2 bung and get to wiring.

I had a set of Hooker 2055 shorties on my LT1 and had no problems at all. They fit with both the 4L60E and T56 as well as the later 2210 LTs I installed.

Re: cant find LT1 headers???
I haven't heard of a third gen SBC header NOT fitting a LT1. Yes, the ports are different, but go with a 1 3/4" exhaust and it will be fine. Even a 1 5/8th will still technically work, and probably not be all that bad off.

Re: cant find LT1 headers???
I was looking at something like these or around that price range for now till I am able to afford to have a better exhaust system done. Will these work correctly?
this is about the most I want to pay for them atm
