Ok so I've been gone for a while and forgotten most of my lly knowledge lol. My 05 lly needs head gaskets. I planned on pulling the engine to do it as I want to head stud it too. What are some things I need to look out for? And can anyone recommend a machine shop in NJ to send the heads too? I know this has been gone over probably countless times since I've been away lol. I just can't do a search right now cause I'm at work.
