2005 Honda Pilot Timing Belt

I used a local garage for the first time a year ago, he did a Timing Belt replace, after a couple days I called him and he told me he “my arm slipped while adjusting the timing and the Cam popped out” so, he told me he would replace the head with a salvage head at no cost. After that the car ran reasonably well but I noticed he replaced the back 2005 head with a 2009 Salvage Head, a different Honda year series. Does any of this sound right. I only noticed when I attempted to change the plugs and noticed the two different heads.
