what vehichle is it for? if it isnt something like an acura with a small block (ive seen one) they probly make full length headers for it. I know they make full length for small block for most every gm vehichle with a stock small block. they make them for jeeps and s10's with small blocks so i wouldnt be surprised.

P.S. Block huggers are Horespower robbers (of course better then stock manifold but they dont make as much HP as full lengths do).
