Pugmaster, I am well aware that the exhaust manifolds on a 440 (or 413 or 400) are Nearly Impossible to work on, due to Clearance Problems. That's the very Reason to Trash them, and get the Exhaust Headers. However.......... they are only available for 1977-1981 Class C's. I refer to Hedman "Hedders", Part # 79220 from Performance Automotive Warehouse for Aprox. $200 or less. (Also, for the small block 273-318-340-360 's there is the Hedman Part. # 79030, for Aprox. 150 or less.) AND, there are other Models for Class A Dodge MH's.
