I cant get my headers in, I worked all afternoon but just cant get them in. I tried going in from the bottom, didnt work. I tried from the top and it almost fits. So whats the trick to these things?
No instructions as I didnt buy them brand new, but they're in good shape. On the driver's side it slides down and gets caught between the steering shaft and the cylinder head. On the passenger side it gets caught by the wiring going in from the bottom, and gets caught by the cylinder head going in from the top.
I have those same headers on my 85 and they are not easy to install that's for sure but if you removed the two diagonal braces from the front crossmember they should go in from underneath the car with it up in the air.

Well I had that sucker up high enough to put cinder blocks underneath the tires. I didnt feel comfortable with it being up so high. That sucks that I have to take the braces out, but if thats the only way, then I guess i'll try that.

Do not crawl under your car, if the only thing holding it up is cinder blocks!
Those things have been known to crumble under the weight of an auto.
Even a Corvette is too heavy for their use.

Note: when you remove the cross braces, the nuts in the center of the car are on the same bracket. There's two "studs" on them so you have to take both out for the brace to fall out.

Oh crap, no it wasnt sitting ON the cinder blocks. I had the car jacked up and the jack stands as high as they would go on both sides. I put cinder blocks under the wheels cause it never hurts to have a back up plan should the stands or the jack fail.
I'm not so sure about taking the brace things out, looks like part of the frame to me.
The braces MUST come out. The car won't break in half while your installing the headers. I've had mine in & out several times w/ headers, oil pan, rebuild, etc etc. over the years. They are a brace, nothing more, nothing less. Some earlier years have smaller versions or none at all.
On my 86 the diagonal braces are a piece of cake to remove. There are two of them that can be removed individually.
If yours are the same, they begin toward the center of the engine and move outward, diagonally. About 18" long, give or take.
Only two bolts on each, one at each end of the brace. If I remember right, the center bolts call for a 15mm socket, can't remember about the outboard ones though.

Removing them is no biggie.

My hooker long tubes fell out without removing any braces last week when I was yanking the engine. (literally, I unbolted them and they fell on the ground).
Do you have pix of these braces? i'm curious if my 87 is missing them...
Can't miss them if they are there.Two pieces of scrap metal from center of front X-member to frame rails level with 2nd cyl back.
In '87 at least they were part of the Z51 handling package , unsure of when they became std fitment.

Here is two pix of my car, one with the motor out, and one with the motor in (the first time) and the long tubes. can you point out what I'm missing or being retarded about?

Yeah thats how mine are, looked like just two bolts but someone else had mentioned that you had to remove a lot more to get them out. I'll take a pic while i'm under there working on it.
Alright, i'm back with good news. After removing the cross braces I managed to wiggle them up in there. BTW they are 2 seperate pieces with a 15mm bolt in the middle and a 13mm bolt on the outside, oh and its a lot easier to remove the middle bolts and then the outside bolts.
Ok moving on, with a new problem, they're in there but the bolts wont go in! The head of the bolts run into the runners, doh! So what kind of special bolts do I need to put in there? I was using standard length and size header bolts BTW.
