Yikes man the one side of the head doesnt look very good.Might need some machine work done there.You can definately tell inside the cylinders where they were crusted up bad.I dont think those pistons would clean up well either they would probaly be pitted up pretty bad.The cylinder walls dont look that bad so you could probaly get by with a good hone job.Dont use a stone hone either if you attempt this.Get the ones that have the beeds on them they do a better job.The stone ones just remove the glaze while beed ones will give you that criss cross pattern.Keep us updated with lots of pics.
