Header pipe re-install into chamber trick?

[coreyoreo]

Hey, all, I'm reinstalling my headers after replacing the exhaust gaskets, & I did number the pipes 1,2,3& 4. (At least I think I did. I laid them down in that order.)

   They all look alike side-by-side, bend & length-wise, with the exception of the little drain bolt(?) on each one, 2 pipes have one dead center facing the ground & 2 facing off center to the ground.

    Since the pipes are all shaped the same, but the chamber has 2 different levels for insertion, (2 outside are higher, 2 inside are lower) is there a trick to installing the pipes without putting too much strain on the pipes?

Or do I just need to loosen the chamber enough to fit everything in & then tighten everything up? I'm afraid of bending or tweaking the pipes... or worse.

Thanks again for helping this newb out!!!

Ah crap....    Hate when I do this.

After closer investigation, turns out that the pipes are indeed different. The 2 inside pipes are bent a tad lower to accomodate the lower ports to the chamber.

Note: The 2 inside pipes are the ones w/ the little drain bolt off center to the ground.

Hope someone else learns from my mistake.

Back to the job at hand!!

Look closely at the stamped numbers on the bottom of the pipes...They end in a 1 or 2 or 3 or 4... that's the cylinder they go on...
The bottom bolts are for oxygen sensors which are used for fine tuning the fuel/air mixture.

I'd like to lend a visual hand to Pats answer.
I found these numbers when I was in the process of polishing the header pipes.

Wow, thanks Pat & Leon, I learn something new every time I get on here. Wasn't aware of the oxygen sensor tuning at all.

Nice polishing job, Leon, my numbers were virtually invisible, covered up w/ black paint, so that 's why I didn't notice them. And fortunately, I did get them on the right cylynder.  

One more question if I may ask....

What's the trick to holding the new gasket in place when re-inserting the pipe? Swearing doesn't work... I tried!!

A smear of grease will do the trick.....works with most things. Is even handy on the end of a screwdriver when working on screws in hard to get at places.
