Jim,

There's no need for sleeves AND pistons. Do one or the other. The pistons are very highly stressed, so I prefer boring and using oversized pistons. Make sure that the piston crowns are the same configuration as the ones you take out.

Since you already have the head in shape, this would not be too expensive. Just strip it, bore it put in the new pistons and maybe bearings. The bearings in my daughters car and the crankshaft were absolutely perfect, so I carefully marked them and put them back exactly as the were. The engine still holds great oil pressure.

Best of luck,
