Scored or leaky lifter bores can be repaired with GMPPs sleeve kit. Lifter bore sleeves are also recommended for competition engine builders who "blueprint" the lifter bores. Drill the defective lifter bore to 1.044". Shrink the sleeve by cooling it to -40 F 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" hole through the oil gallery and finish the sleeve ID to 0.8432/0.8442". The sleeve can also be predrilled with a 1/2" oil hole before installing it in the block. B. 88958652 Valve Lifter Guide, "Quick Cam" This composite lifter guide is the same as used on LS Series GM small-blocks, but with mounting holes for use on Gen I GM small-blocks. For use with hydraulic roller lifters only. The design of the lifter guide makes it possible to remove the camshaft without removing the intake and lifters. There is just enough friction in the guide to hold the lifters in place if the rocker arms are backed off and the camshaft is rotated two full revolutions to push up the lifters. Package services one cylinder head. C. 12371042 Hydraulic Roller Lifter Kit This roller lifter kit is designed for 1986-and-later engines.
