My opinion is, it's not an LT1/SBC. Just leave the GenIII OEM rockers in place. The aftermarket pieces will be heavier and could lead to valve float.
Furthemore, my opinion is don't stay a "stock LS1 with bolt ons". If you run out of other bolt-ons and you're still power hungry, add an LS6 cam.
Not everyone will feel this way, and I understand this.
Lastly, look at all of the high RWHP LSx cars all running the stock rockers. There are plenty.
