Re: ASM headers
If the car being a salvage title isn't the reason for them to not fit, then I would definitly change your motor mounts. My passenger side flange would always vibrate on the k-member and after I changed to some ES poly mounts, no more vibration!

Re: ASM headers
My bad it is hitting the steering shaft. The ASM headers will not fit. Tried everything and still about 1 to 1/12 inches off. Going with BBK shorty's so it will fit for sure I hope. Thanks for all the input

Good luck, the BBKs are a royal pain to fit in there. Mine didn't line up with the stock Y-pipe (off by more than an inch) and the passenger side one bumps the K-member while turning and under load.

Re: ASM headers
There is nothing wrong with those AS&M headers other than bad engineering. I bought brand new RK-sport headers which are AS&M clone rip off's.
The driver side header 1st primary was banging the steering shaft. I ended removing the steering shaft and modding it by extending it to make it longer, this way it no longer hits the shaft.
The passenger side header collector flange was hitting the k-member, i took a disk grinder and did some trim work on the k-member so the problem is gone.
The AS&M headers are great headers but you have to get creative with them to make them fit right. The AS&m's and RK's are the next best thing to long tubes and mine now fit like a glove with no issues period.

Re: ASM headers
Bad engineering is a matter of personal interpretation. My ASM headers have always fit wonderfully in the car. The ONLY time I had clearance issues was after my motor was R&R'd and the stock rubber mounts had been re-used. And even then, the only clearance issue was the Y-Pipe collector flange was about 1/4" from the floorpan and would tap.
Steering shaft cleared fine, K-Member clearance was fine.

Okay, bad choice of words
. I should have stated that there is a thin line between maimum performance and fit with these headers. The primaries are routed for the most HP but they do come close to hitting things like the steering shaft. Again they are great headers and I am not knocking them, just be advised that in more cases than not they do not 100% directly bolt up without having to tweak on somthing especially the y-pipe. From what I have read this also the case with most LT1 headers made by other brands as well.I would still take the RK's or the AS&M's over any other non LT header anyday due to the bigger primaries and ability to accept bigger mods like H&C.

Re: ASM headers
If you are having problems putting the headers IN because the steering shaft is in the way, just take it out. I absolutly had to take mine out to get the headers in. It really is not a big deal, it's almost idiot proof in that it seems to only go back in one way. Just make sure that you don't turn your steering wheel or the rack and pinion or else everything will be off.
Once I got the headers installed, the steering shaft has at least half an inch of clearance all the way around. As Fastbird93 said, the only complaint I have with these headers is the y-pipe flange is about a quarter inch from the floorpan and it does occasionaly vibrate. Nothing too bad, but still kind of annoying at times.
