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

Already have true dual exhaust with Super 40 Flowmasters and no catalytic converter‘s. 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. 

if you are going to use a GM setup get the GM Performance Parts  book shows all perf equip and what works with what  I run  hooker 1 1/2"headers, for the Street the bigger the primary Dia"might rob your low end torque

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.
