Default Timing in datamaster

I've had a chip tuned for me but one thing I noticed seemed to be a high spark advance.

1989 383 superram
58 mm LPE tb
afr 195 eliminator
230/230 @ 0.050 , 0.598" lift, 1.6 pro mags
Hooker # 2149 headers
3.33 gear

Idle = 27 degrees
Cruise = 49 degrees
WOT = 33 degrees

Do these numbers seem to be the norm? Only knock retard @ WOT, which I believe to be false.

Yeah, they don't seem to be too crazy. I see 40*+ at WOT in my LT1.
