Unless the chassis doesn't allow for them, use long-tube headers if you can fit them. Longer tubes help to scavenge the cylinders more effectively at low and midrange engine speeds. Shorty headers are generally a compromise for tighter fits in a cramped chassis or rod with a tight engine bay.

EDIT - Some long-tube headers drop down so low as to considerably reduce the vehicle's ground clearance. If you have lowered the ride height this could come into play even more.

if you are building a mild sbc (less than 375hp) then the difference between short and long headers is not very much. However, if you are building a "high hp" engine then the long tubes really make a big difference.

make sure to use 3/8" flanges (where the headers bolts to the heads.)
