Yes, .400" lobe lift. They said they tested the lifters without a problem, but I used that cam profile in a 440 with Morels, and it had 10 psi warm at idle. Put the previous version of Trick Flow lifters (same as Comps, just less expensive) in the motor, and oil pressure came back to 45 psi warm at idle. If Comp decides to have Morel make their lifters next, we are pretty much out of luck.
