A local machine shop effed up my KA block with a huge gouge on the top of #1 cylinder.

This block is now useless to me since the bore will be closer to 91mm after correcting the machining error. The Wiseco pistons I purchased prior to machine work are 89.5mm. 91mm block with 89.5mm pistons will never work...

I prefer a bare block with or without the front oil pump cover, that has never been machined before. I need a 89.5mm bore size after cleaning up the cylinders.
