For use on Gen I GM Small-Blocks (block must be drilled and tapped)
For use with hydraulic roller lifters only
Makes it possible to remove the camshaft without removing the intake and lifters
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
NOTE: Package services one lifter bank.
