You need to port the hell out of the stock intake system (plenum& intake) after that it's pretty much a standard small block (except for the roller cam introduced in 87)
Don't know if you're wanting to spend more on it than just the N20, or what, head over to thirdgen.org (the ls1tech of the 3rd gen world) and read some of the posts over there (use the search they get really bitchy if you don't)
Just go to http://www.thirdgen.org and you'll know everything you ever wanted to know.
