Oh ok so you dont think they use that coating? If I install new pistons and rings I can just rehone those existing sleeves? I dont have any wear on the cylinders as compression is still good.

If I just put new pistons and rings in without honing it I am sure it will smoke and not have good compression without the rings seating properly. This is the first aluminum block I am doing so not sure what the differences are in how to get the rings to sit.
