1977 L82 with 4 speed. Mild cam, factory heads and intake. At some point down the road I知 looking at putting on Vortech heads and a new intake manifold. 

Already have true dual exhaust with Super 40 Flowmasters and no catalytic converter壮. What would be my best option for headers that I could put on now, that would still work with the new top end later on down the road.

Just had my wife's 77 engine rebuilt. FlowMaster ceramic short header/block hugger, are installed to 183 aluminum heads, with a aluminum intake. The car will then be taken to a muscle car muffler shop and custom fitted with dual exhaust to fit.
