Plug blowout

So on my way home from work the other day I was cruising at 45 in 5th and I heard one of the worst sounds I have ever experienced I had just swapped the midpipe I day before and it sounded like a terrible exhaust leak as if the mid pipe came off the manifolds well after jacking up the car the mid pipe was secure all bolts were tight so I had my dad start it while I checked the manifolds thinking maybe a gasket or the manifold failed, well when it started I saw a flash on top of the drivers side head I instantly told him to turn it off then my worst fear was realized as I saw the plug and coil sitting on top of the valve cover. Now the plan is to get a time cert kit and fix it, I wish I had the money and time to buy new heads but I'm the stereotypical college kid that uses my 2000 gt had a daily, but I noticed something while looking at the plug and this is my question to you all knowledgeable folk does this look like the piston some how hit the plug?
Thanks for reading any help or suggestion is appreciated
2000 gt, 113k, did the plugs over the summer no issues till this happened

To me it looks like it may have hit it and bent it some

Right obviously the plug was gapped when put in, but you guys that have witnessed or had blowouts happen to you are the plugs still gapped after they blowout or are they bent up like this one here's a little better picture Click image for larger version

Hey man, same thing happened to my 02 GT, had just gone over a speed bump nice and slow and when accelerating it blew out. I thought I had blown a rod or something. The spark plug shot right out and looked exactly like yours. I had swapped the plugs out like 3 years prior, maybe just slowly came loose with time. Bought a new coilpack and new spark plug and good as new. I also went around and retightened all the other plugs. Dont want to go through that ever again.

When you "re-tightend" I hope you used a torque wrench on these 4 thread aluminum heads... properly torqued to spec you barely go past hand tight. Like less than 1/8 of a turn.

With that said, you can easily see if that piston is coming up further than the others. Stick a dowel in an unaffected port and measure how far it comes up when you turn the motor over by hand. Then do it for the bad cylinder. If its the same I'd just do the time-sert, all new plugs, torque to 12 ft lbs and call it kosher.

Yes, I made sure they were torqued to oem spec. It has been over a year and 9 months since it happened and I have not had any issues. I dont know what could have cause it other than it slowly coming loose. I have had it I the garage for about 8 months since getting my 2012, I feel bad cause I enjoy driving the 12 but cant bare to part with it. I drove it off the showroom floor back in 02
