1) I am not satisfied with Butler's answer in the least. I have 19 years experience with casting in an unrelated field, and I found their answer patronizing and have not responded.

2) Based on the spark plug thing, it is understandable you are skeptical and think I am leaving some info out. I have absolutely no logical answer to explain the 3 closed gaps. I absolutely did not drop them. I gapped them all at .045 and double checked each. It is ALSO TRUE that there is no sign of mechanical interference, debris, nor combustion. It is ALSO TRUE that they don't come out of the box closed. So WTF happened??? I have no idea. My machinist thinks that I HAD TO HAVE dropped them. I cannot argue with his logic either. I have to move on.

I have been playing with cars since 2016 when I bought the GTO. I am a novice, but I immediately knew there was improper combustion at part throttle. I didn't think I was missing 3 cylinders. I assumed timing or AFR. This was the first time in my life I had ever fired a new engine. I chose to drive it a couple miles before addressing the misfire. On was only misfiring on partial throttle under load. The rest is history.

You may wonder why a novice would take on such a big project. I am mechanically inclined, have good friends with lots of knowledge, and have successfully done all sorts of work on the car. I thought it would be fun to try. Guys have been rebuilding these engines in their garages for 50+ years, so why not me?
