Edelbrocks Mid-length header is a good compromise.

I have a set on my '95 pickup and they fit great. I really don't think you would have a fitment problem with any of the small block truck applications. You may want to compare a set to your current long tubes but these are short enough that they don't get into the floor pan.
I will recommend JetHot coating them also. Best money you can spend for performance and longevity.
