Yes but watch out for detonation. The EGR equipped engine usually runs a lot more ignition advance without detonating. See what Chevy used for timing before EGR and you will be in the ballpark.

I'm missing something here: Long tubes vs EGR valve?

There should be no compatibility issues with EGR and headers. SBC EGR valves are fed exhaust from the internal crossover, only issue is with Vortec heads that would require an external exhaust feed line to be installed.
