My exhuast is a 2.5" setup with a crossover. The heads will have some porting done on them but not much. Any header recommendations? Dougs? Shorties? Full lenght? I like the LB manifolds from Ram Air Restorations. Anyone using them? So 60-80 HP from logs to headers? Thats alot!! I will install a high torque mini starter to help with hot starts. Don't want any clearance problems. Thanks.
