Alright. I do need new headers because the guy who owned my car before me put some REALLY cheap ones on and I've never seen flanges so warped. If you all say I should rethink what headers I get, then I guess I got some more shopping to do. Is fitment on the plugs the only thing I need to be concerned with?
On a related topic: I was thinking. Would I be able to hear engine ping with a bad header leak? I thought I'd be able to hear it, but that header is pretty damn loud. I feel like I have advanced the timing a LOT (previous owner painted the engine, including the harm. balancer, so even if I had a light, I couldn't see how much timing I have). I ended up turning the dist. a little more than 1/8 of a turn, and it still backfired out the carb late last night. Granted it only did it once all day, as opposed to every time I took off from a light and when it starts, so it's getting much better. I'm pretty sure it has a vac. leak, too. It idles really high in park, and really low in gear. And when I shift it into drive or reverse from park it lurches (sometimes chirp the tires). I'm afraid that I'm doing some kind of damage to my engine my advancing the timing more, but that backfire yesterday made me think that's what it needs. Any thoughts on anything?
