Everything else is right on and Im confident.

Is it worth it for me to get the car judged as is and then add stock parts?
Deductions for Exhaust:

6 pts originality, 4 condition for Exhaust manifold & Catalytic converters
10 pts originality, 10 condition for Exhaust pipe and resonator
5 pts originality, 5 condition for Clamps and Hanger brackets
12 pts originality, 12 condition for Mufflers and exhaust tips

total points 64

Deductions for Battery:

20 pts originality, 15 condition are available. If you have a new service replacement AC Delco battery the worst you should see for a deduction is 1/2 of the orginality points or 10. This is a standard deduction from the judging reference guide.

Deduction for Transmission shifter:

10 pts originality, 10 condition for Shifter & knob
5 pts originality, 5 condition for boot


total points 30

This info is from the 1990/1991 judging sheets Revised 8/2005. 99 point deduction from a total of 4510 is 2.2%. So if you drive to a meet 220 miles from your home you break even.
