Help! Headers 67 dart 340 brodix heads

The heads are kick *** and the exhaust ports are raised and the plug angles are different. Maybe I should just remove the headers and have them copied.A tube goes thru the fender well on each side and they started as hedman huslers their functional just looking to dress it up a bit.
My Hedman Huslers all the tubes(1 7/8) run through the fenderwell,but then again mines an Early-A.
