Quote: My Hedmans are already leaking from the flanges and was looking into maybe the new TTI 1 7/8" A-body race header or the Hooker 1 7/8" header. What are the opinions on the two? 3" collector or 3.5" collector?
Which Hedmans do you have? What gaskets? I have them on my Dart with Fel-Pro gaskets and have never had any issues. Mine have one tube that goes through the fenderwell on each side, 1 7/8" with a 3 1/2" collector.
