I recently purchased a 83 camaro with a 383 stroker, the motors fully done up. heads cam forged internals. The motors got only 3,000 miles since it was rebuilt. I'm lookin for the best possible spark plugs out there for the 383 stroker regardless of cost. The car also has MSD Ingition installed. Currently its got Edelbrock headers but I'd like to replace those with something thats not going to rust, and adds the most power. For the headers, I'd like a couple options if anyone has some. Thank you in advance for the help!
