Help with Header choice,please......

I have a 1968 Dart GT.It has a 383 in it with a 4 speed.It has an after market,universal bell housing.Things look very tight.It has Fenderwell Hooker Super Comp. Headers on it now.Is there a Header that will work for this application? I had a 67 Dart with a 440,auto.It had TTI,2" Primaries and they fit great.I want to loose the Fenderwell Header.If i am sol on the Headers,are there Manifolds out there i can buy? Thanks Guys..
