Jeff,

You can only run your '88 as a 138 HP engine with the .921" lifters. I'm sure there is great deal of latitude taken with the "Aftermarket OEM-type lifters permitted" statement by those who like to stretch the rules, but I was told when building our 138 HP Cutlass Stocker, that I had to use the "big" lifter, so we did.

Fortunately, they're able to be shimmed for limited travel, and unfortunately, they're heavy and require the 138HP roller block.
