Broken rocker arm after plug change????

Broken rocker arm after plug change????
Guys, I need help here. I'll do almost anything mechanically but with all the hassle on changing the '06 5.4 plugs, I'd let somebody that has done a ton of them do it. I asked around town and I took it to the mechanic recommended by several guys I respect and the shop has been there for over 20 years.
My '06 Mark LT has just over 70,000 miles and he assured me he would get them all out cleanly. He broke three and all was well as I left the shop, almost $600 later. He has extreme difficulty with # 8 and the truck was in the shop for nearly 3 days.
Less than 50 miles later the truck suddenly idles terribly rough. I barely make back to his shop thinking a coil came loose, or a plug wire came off or something very simple. He called me yesterday to say that all the basic checks are fine and he suspect something mechanical. Monday he is pulling the valve cover as he suspects a broken rocker arm or some issue in the valve train. I suggested to him that this issue had to be related to what was done to the truck. He says no, Ford has had an issue with rocker arms and it's just a coincidence.
Is this possible???? I'm a pretty logical guy and this coincidence of having a mechanical issue with a truck that has been perfect for 71,000 miles and then breaks a rocker arm 50 miles since the plugs were changed out sound to me like the odds of getting hit by a meteorite twice in the same weekend!
Thoughts, or comments??? I think a piece of the plug remained in the cylinder, jammed in a valve and broke the rocker. Am I wrong????

Sorry to hear about your trouble! Start buying lottery tickets and hide from the meteor!
I changed the plugs in my truck, drove it a week, and the cam phasers went...had them changed and a week later, the truck started running real bad...took it back to the dealer, and they say it needs a new engine...Is it something they did? who knows...I have 100k more miles than you...I have been trying to find anything else that would explain why it idles and runs rough...
I hope you only need a rocker...but be prepared for more! Hence playing the lotto!
Regards!
