sorry to hear about that white smoke. It's not a very good indicator. When the head gasket went in my car I decided to get a used engine instead of rebuilding it. I had 110k miles at the time. When I got the engine out and the heads off I found the block was not flat. The used engine was less expensive then getting a short block. It was was also quicker then getting the block remachined. How much are you willing to spend?
