Note:The lifter bosses in SHP blocks are .220" taller than the bosses in early-style blocks that were not designed for hydraulic roller lifters. If you are installing aftermarket lifters with link bars in an SHP block, the lifters must be designed for use in 1987-up or Bow Tie blocks.

Due to the additional length of these aftermarket tie-bar lifters, they must be installed in the block before the cylinder heads are installed.

Emissions Note:

This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.
