1989 Honda Accord Blown Head Gasket/ Engine

Over the past year I have had anumber of cooling related issues such as over heating, replacement of hoses, thermastat, sensor, a/c no longer works, ect. It started leaking water by the drivers side of the engine block.
The car was looked at by a friend who told me that he had a cracked/warped header, the engine sounds hurt and there is significant condensation coming from the tail pipe. The car is worth around $2,300 accordign to kbb. Com.
I decided im not going to fix it, what should I expect to receve for selling it in this condition? Should I sell it as is or fix and then sell?
