Yes good finish and straight, my concern when looking for pistons from the big engine builders, they said they never go over standard (4.5) because when bored there’s not enough material left between the cylinders = blown head gasket. I guess they made throw away blocks. Then the other can of worms is if all 8 holes are sleeved how weak-thin will cylinders be then (Siamese block) I feel like I’m in no mans land. I have everything there for this engine waiting now in limbo. One other thought, can standard pistons be coated .030?
