Header for a-body 440

Have a 540 cu.in. in an a-body with Indy max wedge heads. What header can I use that has no access problems to spark plugs. The headers I have now have has #7 and # 8 tubes exiting through the fender well. The #6 tube to head clearance will not accept a normal spark plug, maybe a shorty plug but still no room for the spark plug wire. Do not know who made these headers. Help!!
