You're probably actually asking me, not dmcman73 since I started the thread. Yes I installed the NGK 2238's, I gapped them right in the middle of the recommended range, and put a dab of antiseize on the threads with a brush before installing. I probably only put 50 miles on them before starting a new project where the car is laid up for a while but they seemed to work just fine. Based on that and other's experience I'd say they are a good buy.
