Hi all, I have a 1990 F250 351 EFI E4OD 4x4 and wanted to know if anyone has ever had any good or bad issues with shorty headers on a 351 using plumbed headers. I found a set of Hedman Headers that claim to bolt to the existing stock y-pipe and are compliant for the emissions. These are stainles black painted for $215.00

Any comments?
Thanks Larry
