1971 Dodge Dart Swinger 340 header question

Tti-not again.70 duster,power steering,4-speed,7qt.moroso pan on a 340.bought tti340a-c5 coated headers from Mancini 710.00 show price at Norwalk.the fit flat sucks if I have to distort them to fit and the still hit . How much are Doug's?cause I'm gonna use them on a 71 manual steering-automatic instead.what a waste of cash.but hey ,they look real pretty guess that's what counts the most,because they won't stand behind them after the sale.even when they only come with 1 gasket and 6 bolts in a sealed box
