I ran the Summit shorty truck headers on my 93 e150 5.0. They are listed for an f150 but fit fine and are probably your easiest option for headers. I dunno about block huggers.
Did Some Checking On-line Looking For Block Hugger Headers. The Only Ones I Found Was Hedman Hedders For An F-150. No Other Source Has Been Found My Me And Those Were For A Chevy. I'm Waiting For A Rep To Call Me Back On The Ford Applaction. Will Post Results When I Find Out..
