Re: Header Help
Yes, there are 93 LT1-specific headers. The only real difference is the location of the AIR and EGR connections. Basically, the passenger side header has the AIR and EGR connections combined in a single connection, where the 94/95 passenger side header has individual connections. If you are deleting AIR and EGR, you can use 94/95 "non-emissions" headers.
There are short, medium and long tube headers available. In general, the long tubes will produce the best results, but they have the added issue of being a tight fit and reducing ground clearance on the driver's side. The most popular long tubes are Pacesetters. Decent quality and performance for relatively low $$$. If you want the highest quality, look at Kooks.
In my experience, shorties offer the least performance gain. I had a set of JBA shorties, and they were good for low end torque, but really seemed to strangle the engine above 5,000 RPM. Currently running AS&M mediums, but they have been significantly reworked to allow true dual exhaust, rather than the typical Y-pipe that wraps around the front of the oil pan. But they are the best of the mediums, in my opinion, and have been shown to be capable of supporting big HP.

Re: Header Help
Like most things, you typically get what you pay for. I ended up saving for the best (to me) and did it right one time, instead of going through a couple cheaper sets. I installed coated stainless Kooks long tubes, and they have been perfect. I am sill running a stock height suspension, and the only time I have clearance issues is with those BIG speed bumps you see in shopping centers... I just avoid them. Other than that I have never touched down with mine. Almost 3 years later they still look like new and have yet to spring any leaks. I went with the full AIR/EGR with the high flow cats, and 3" Y-pipe, and performance was very noticeable. I had many other mods made at the same time, and then had the PCM dyno tuned. If you go to the work/$$ of adding headers, spend the extra money for a good tune to optimize you new addition.
