Well first of all, i wouldnt spend $2,500 bucks if a new block w/ warranty from dealer is about $3,250-3,400 bucks w/ core return the warranty is good for 36k or 3years, spend the little extra cash and have a brand new engine... dont get stuck with a $2,500 plus job and a 130,000 mile engine and wait for the other head gasket to leak. Do it right the first time.
