Innovate Motorsports wideband O2 system installed! Question about 6bbl intake

Data is a wonderful thing,but you still need to verify what the gauge says and read plugs. My afr reads 14/13 @ wot and the plugs says it's fat So reading the plugs is the tried and true way and what your AFR reads is what it needs to be even if it tells you it's lean.

"Reading the plugs" as it was described to me, meant doing a quarter mile run, immediately shutting off the engine as close as possible to the finish line (like off the side of the return lane) and pulling them asap.
It's hard enough to change the plugs on a cold engine, much less under those circumstances.
So, is that process "correct" and regardless, are there other ways that can deliver a worthwhile result?

You can get a good idea by making a pass and pulling just one plug. It doesn’t take long to pull it but you really need to cut it to expose the porcelain to read it, at least I find it much easier that way. With your dual plane intake, multi carb setup, making pulls on the dyno to tune it might be easier.

I jet for mph. Let everything else fall where it may. When I do this, the plugs always look lean to me, but the A/F always seem to be lower (more rich) than what everyone targets.

The chassis would work best for WOT jetting and finding the ideal timing.

The shop that installed the O2 sensor system has a chassis dyno. There is another one, a Mustang chassis dyno about 50 minutes away and I know the shop owner pretty well.
I think I'll give the shop that's 20 minutes away a shot first, but I have to ask about prep time. The local shop counts strap and prep as part of the session for billing. I would have never thought that should be the case.
Anyway, I have some "tinkering and tuning" to do first, and maybe grab a jet kit too, and then go see what is what.
I am especially curious about the HP curve, because my butt dyno says 6,200 RPMs should be redline, and that's where my limiter is set, shift light at 5,800.
Once I get the 3 Rochesters back from the Pontiac pro, I want to bring my wife's GTO too.
I am going to turn around and wake up and it's going to be the first day of Cruisin the Coast, even though that's October 6th, I know it's not that far away with all that needs to be done to both cars...
