I've decided to throw some money at my old reliable daily driver...a '97 Chevy Silverado. It has the 5.7L Vortec with about 200,000 miles on it (mostly highway) and it's still going strong. I was thinking doing the obvious first upgrades...cold air kit and headers. It already has a catback system on it, so the headers would complete the free flowing exhaust.

My question is this: Which headers would be a basic bolt-on replacement for the stock exhaust manifold? Shorty headers? I'm looking for a straight up replacement with no modification to the existing exhaust system (in other words, connects to the collector that is stock on my truck without other modification)

I'm looking at Summit Racing for parts, and their headers (and probably everyone else's headers also) come with the gaskets and mounting hardware, so it seems that I can just do a swap...exhaust manifold for header...and be done with it.

I don't have the tools (welder) to modify the exhaust that I already have, so that's why I am looking for a bolt-on replacement...thanks, guys.
