My buddy is slowly backing out on buying my engine so... What should I sell a 99 head swap for? What all do folks expect to be included for the swap? I've never done the head swap myself so I'm not sure of every little part that would need to be included. Engine runs/ran fine, I have video of it running before we pulled it. I'm going to check it out and make sure it's solid obviously before the sale. Assuming it's good to go, what's market value?
