any of the hooker long tube headers would look good just don't get the coated headers ie jet hot coated etc. now for valve covers i'd go with a set of M/T polished aluminum covers those are really period correct and would really set the engine off in that old school look.distributors i think mallory either unilite or the dual point with a hyfire cd box and coil. my motor in my 72 camaro has that old school/ day 2 look also. for a sbc i've got old cal-custom finned valve covers and t-handles,flex a lite green fiberglass fan,edelbrock scorpion intake ,holley 850 DP and mallory unilite ignition. the only thing is the headers i'm running hedman shorties due to ground clearance issues with long tubes
