Goodson's Honing Stones and Silicon Compound will fit both the Sunnen AN-112 and AN-815 and the Goodson HN-218 and HN-2118HD Portable Honing Mandrels, for honing high-silicon aluminum-alloy blocks. Use each stone set progressively until the final bore size is achieved. To create the final condition, coat the felt set and the honed cylinder surface with the Silicon Compound and lap the cylinders. The cylinder will have a dull matte finish and the piston and rings will ride on silicon instead of aluminum.
