Header install issues
sorry, I know it's an old thread.
I ordered a set of longtube headers from Stainless Works and tried to install them...the hole didn't line up and Stainless Works said their parts are good so they sent me a refund instead of any repair. So I ordered Maximizer long tube headers off ebay for 1/3 the price. Now the neither side lines up with the holes (head and header). When you installed yours did the holes on your new headers and the holes in heads line up perfectly or did you bore the holes out on your own to MAKE it fit.
I'm going a little bonkers over this...If I start wollowing out the holes on a brand new part I void the warranty plus...I paid hundreds of dollars to get a bolt on product....I need to know if everyone just suffers silently and wallows out the holes when they get them.

1993 LT1.
So, I installed a set of long tube headers over the weekend and they do not have the AIR pipe fittings.
I pulled the pump located in the drivers fender, the hose from the pump to the bypass valve, the valve itself and the hose from the valve to the metal air tubes on each manifold. There is one vacuum line on the bypass valve going to the intake manifold and an electrical connection. It was my understanding that everything running from the air pump was fair game to pull out.
Well, I got around to starting the car up and it has a "check engine light".
Pulled the code and I get H26. 'H' obviously meaning history, but the 26 refers to this:
Code #26: Quad-Driver Module #1 Circuit.
I was under the assumption on an OBD 1 car I would not throw a code.
Any ideas?
