What headers will fit and what are my best options?
I have an 89 trans am GTA with a 5.7 350 TPI. I’m looking to replace the headers but have never done it before and not to sure what will fit and what won’t I believe the headers I have now are just stock. I’ve been looking around and there seems to be all kinds of options but don’t want to end up ordering the wrong ones. Also I don’t currently have a welder. Will I have to have anything welded on during installation? I don’t have much experience so any information helps. Thanks

If it has headers on it it's not stock, they came with manifolds, and yea, do a search/look around, this has probably been rehashed thousands of times.
