I've had multi-point sequential EFI on my '66 GTO since 1998 and would never go back to a carb.
For a Pontiac retrofit, I really don't see the value in sequential EFI... batch-fire would be just fine and if I was doing this again, that's what I would do. There's no way any of us has the patience, dyno time nor $$ to accurately set up sequential injector timing throughout the engine's range. But if you have your heart set on an LS ECU, then of course you'll have to come up with a way to measure the camshaft TDC for the sequential part. I did it by modifying a small-cap HEI from a TBI SBC truck engine.

That's the kind of inventiveness I was hoping to see. How is it for reliability, performance and gas mileage compared to carburetion?
