ALL  LIFTER BORE REPAIR KIT - Part Number 14044875
Lifter Bore Repair Kit Small Block V8 Gen I & II & 90 Deg V6. Don't scap an expensive engine block because of a damaged lifter bore. Scored or leaky lifter bores can be repaired with GMPP's sleeve kit. Lifter bore sleeves are also recommended for competition engine builders who "blueprint" the lifter bores. Note: Drill the defective lifter bore to 1.044-inch. Shrink the sleeve by cooling it to -40 degree fahrenheit and insert it in the lifter bore, making sure that the bottom of the sleeve is flush with the camshaft cavity. Drill a 7/16-inch hole through the oil gallery and finish the sleeve ID to 0.8432/ 0.8442-inch. The sleeve can also be predrilled with a 1/2 in oil hole before installing it in the block.
