Powdered metal valve seats Kibblewhite

Thanks to powder metallurgy technology, a specific alloy creates a high-density seat with exceptional wear resistance, machinability and thermal properties. Track and road tested, for high-revving multivalve applications, with leaded and unleaded gasoline, ethanol, methanol, naturally aspirated and supercharged Made in the USA All applications use two intake seats and two exhaust seats, unless otherwise indicated.
