    Berg's seats are made of high strength 4340 chrome moly, heat treated to C32-34 Rockwell and are compatible for unleaded fuel. Straight OD and with minimum starting lip to give maximum seating area. Gives more life and will not chip and crack like cheap cast seats. Can stand press fits up to 0.015". Designed to use standard size cutters such as 1-1/2" cutter. Press size is added to the OD of our seats. All seats are 0.385" deep to ensure hole clean up. Made in the USA. Sold per each.
