Need some advice

So let me start this off by saying this is the first car, I've ever started to build so a lot of first for me.
My next step in the build would be forged internals, transmission, Speedtech s3/4. My main concern is the transmission.
I daily the car so I still want some drivability. I have seen a lot of talk about the 550, and AT transmissions, but nothing on sequential.
What could hold and be reliable at the 600-750 whp mark while leaving wiggle room for more power.
