Any issues to address while installing headers on LT1?
Hey all. As most of you have probably already seen, I am in the process of purchasing a '97 SS w/ 34k miles. One of the first things I plan to do is finish the exhaust. Currently has SLP 2OTL and SLP CAI. As I learn more about the LT1 and the cramped engine bay, are there any other things I should address while doing the header install? I am reading that the headers are very close to the spark plugs. Would it be wise to replace the plugs while doing the headers? Do any of you LT1 guys have suggestions on any other things that should be addressed/assessed/replaced while doing the headers?
Thanks
Thanks

Changing the plugs when the old headers are removed is the perfect time. You'll have a good visual shot, and won't have to work blind.
Good luck with the 97 SS.

97 with 34k miles - odds are the plugs and wires have never been replaced. Might want to do that. Passenger side hoses can be a pain with (and without) headers, check those too. I know my passenger side wiring needed to be wrapped and strapped with my hooker LTs, check that as well. IIRC, my starter wires needed to be rerouted to stay off of the headers too.
Go slow and watch everything is the best advise. What gaskets are you using? I've had great luck with Percy's, check Summit or your local auto store.
Edit - don't forget to be careful with the plugs, aluminum heads are easy to crossthread

Glad to hear it. I always tell my kids, "do it right the first time, every time". Shortly after that, I usually get flipped off

Your earlier post indicates the car came with a set of Hooker shorties that had not been installed. Is this what you plan to install? Are they single-cat or dual-cat? Are they CARB-certified? Do you have to pass a visual emissions inspection, that would detect elimination or relocation of your current dual-cat configuration?
Do the headers have emissions connections (EGR and AIR)? Do you plan to retain those systems?

If they do a "visual", I would expect them to check the number of cats - you are supposed to have two - and the location of the cats - they have to be in the stock location.
