I didn't think they were too bad either. And the car's ET/mph seem to have held up very good also.

This is what I measured using the same gauges when the motor was new. This is after the initial break-in only (no track time, and cold engine:

#1 97 psi, #2 96 psi
#3 96 psi, #4 96 psi
#5 97 psi, #6 95 psi
#7 95 psi, #8 96 psi

Those new numbers really amazed me at the time. They are Dykes rings, 0.031/0.062 stepped.
