I always overfill my LS1 and LS1 by about a quart anyway. Maybe it's just a GTO thing (with the front sump oil pan). Never a problem.
But if you are using quality oil in the correct weight you shouldn't need any additives.

Most people with C5s run 7 quarts in the batwing pan.

In the case of C5 corvettes it doesn't have anything to do with WOT.
I know two people that have destroyed LS1/6s in C5 corvettes from being low on oil. One Autocrossing and another at an Open Track Event.
With C5s and stock oil pans it is a very real thing.
IIRC GM themselves sent out an information notice to increase the oil quantity for spirited driving.
I'm not sure what you are getting at? The OP isn't worried about sucking the pan dry. He's worried about over filling.

Depends on the what the car is being used for, the pan, any windage mods, etc.
If adding one quart is good, why not add 4?
What works on a dyno, might not work for a autocross car, or drag only on car.
My point is, without any actual impercial data, which most people on this site don't have and either repeat what they've heard or what they feel. You don't actually know.
We may not have actual data, but there's a Helluva difference between adding a half quart (C5 manuals usually call for 6.5qts of oil) to reach the total of 7qts, and adding a gallon of oil. I know you know this, so I don't know exactly what you're advising here. If the OP has a C5, 7qts is a good idea. It has worked for me, and others, for over 15 years without oil frothing/foaming.

First off, if you are dumb enough to add an extra gallon of oil to you your car(grinder11 I know you aren't) then you deserve what you get.
I said it to prove a point, which was obviously over the readers head.
Also, no one said the OP has a C5...if you look at his sig, he has an F body. However, that can't be assumed.
The batwing pan was mentioned in a ancedotal comment an attempt to validate thier thinking.
All I said was, if you aren't logging your oil pressure you don't know for sure. Why is that so hard to understand?
You never cease to disapoint me LS1tech...
The batwing pan was mentioned to show where an extra quart was added there and it didn't hurt anything. What the OP is talking about is less than 1/4 of a quart of oil here and it's not going to hurt a thing. If OP who merely asked the question and probably now sitting on the sidelines 
was worried about the extra 0.2 quarts they could've added this additional additive or reduced the engine oil by that much and it still would not hurt a thing and BTW not ALL additives are a bad thing, ZDDP additive protects engine parts.
