I have 1 7/8 ARHs on my bone stock LS1 and she makes plenty of torque, including over 300rw as soon as the dyno starts measuring.
Get you a good tune and you will gain everywhere. This is especially true since you are putting together a pretty stout combo...let it breathe.
Fitment may be an issue, may not be. Each car is a little different when it comes to 4th gens. 1 7/8 and up, some will need massaging/notching, some slide right in. Make sure you get poly motor mounts.

Based on what?? Someone is buying the old wives' tale. This absolutely does not apply to LS motors.

So is 750 shipped a "steal" for Kooks 1 7/8" x 2" SS headers?

$750 is a GREAT price for the stepped Kooks. My 1 7/8" NON-stepped (that i never got to use, traded for 2") were close to $800. The steeped headers are WAY more expensive due to the extra larger diameter tubing and manufacturing time. $750 is a steal.
