Getting a motor rebuilt

So i had to go on a road trip today to pick something up from my grandparents and it was about 4hrs total, anyways on the way back the car started to sound like I was running open headers, it was misfiring, then I couldnt even pass cars on the road because i had pretty much no power at all. I cant get a video clip cause my mom is on a trip and took the camera and i cant get a clip. http://www.youtube.com/watch?v=crPZy...eature=related
this was from a while ago that i never got fixed because i thought it was just the chain tensioners and didnt really it drive it unless i had to. But know I think i truly ****ed it up.

Pretty much Im guessing that I ****ed something up and its going to need a rebuild. Any reginians now what shop to go to or ideas
