Pull 3 degrees and check the plugs. If there is no timing mark or it is at the tip add it back in a degree at a time until there is a timing mark or until the car slows down.
If it speeds up from the 3 degrees being pulled then you know what it wanted even if the plug shows you have more lead to play with timing wise. A lot of the old nitrous guys will tell you don't chase the timing mark as long as it is in a comfortable region(before the bend).

New plug pictures.
62N 38F 20 degrees total timing BR7EF plug gapped at .030 50/50 sunoco 93/110.
Here is what I see. Timing mark on the tip, starting to show good heat on the tip also.
I think the motor will/would run best like this. Although it did take 3 passes on this set of plugs to get this heat and timing mark to show.
AFR was 11.9-12.0.
I was more worried about getting the car to hook than the tune-up yesterday since the plugs looked pretty decent.
Once I get it to hook, I am going to start leaning it out. I'm pretty sure once I lean it out it won't take 3 passes to show enough heat to read the strap. Porcelain was nice and white with a slight light green(fuel color) ring at the base, very very faint.
I'm missing a plug, don't know where it is so here are 7 of them. And for you smartasses those aren't my hands holding the plugs

[QUOTE=Fbodyjunkie06;16299771]New plug pictures.
I would have thought a 62/38 mix would be VERY rich too
plugs hard to discern without porcelain view, but still whats up with a check mark by Rachel's name? : )

Just noticed something this weekend.
When running N/A the AFR is very flat. Car was pulling easy 10.8s in 90F+ temps. On nitrous it starts around 11.5 AFR and then goes rich (almost linear) towards 6800rpm.
In any case, N2O solenoid has been replaced w/25amp Nitrous Outlet piece.
I think the progressive may have abused it a little and also the one on there was an older style solenoid.
wish me luck for this weekend cuz its testing time again. : )

Should I leave it alone tune-up wise (82n/40f 58psi) with the correct(900-950) bottle pressure and see what it does and go from there?
Or would you pull one more degree still and go from there. I'm only at 16* total timing on the 82/40 tune-up and a pretty heavy mix of 110/93 with almost all of it being 110. I may start running it solely on 110 alone. It's 7.00 a gallon and I only use 2-3 gallons a session.
