I have been havin' problems with my Integ recently and am looking into swaping out my ls engine for a B18 possibly c5. I was wondering what the cost would be to have my engine rebuilt with a head swap. I'm lookin' at spending at least 6 or 7 g's for a complete engine swap but I don't know how much it would be for a rebuild. What am I lookin' at spend for that. (rebuild the ls) Possibly save a few bucks? Thanks to those that know.
