Don't worry about it, man. I just got hammered on another thread here for gapping my plugs on an unmodified engine. Happens to the best of us, no matter how careful we think we are. Sounds like they are just saying, get busy tearing it down if your not willing to scan it. But if you COULD scan it you SHOULD, "scan" what you "can", first. On with the resolution. That's all.
No big deal. My 2 cents. Good luck.
