You can run Hyd. rollers on just about any solid profile lobe. Most Hyd. profiles are actually more aggressive anyway. With regards to the Comp lobe master catalog, and depending on how big you want to go you could use the TK, CSZ, DSZ or even the QRI lobe families. I typically look and the lobe aggressiveness and comparing the duration @ .020, 050, and .200 against each other to get a feel for what lobe offers the most area under the curve to work within the overall lift and spring restraints you will have to deal with.

All this is good in theory but the limitations are with the spring you can run with the hydraulic roller lifters. Most of the time you can't run the spring you need to take advantage of the larger lobe profiles. In any case, you are probably going to have to run a short travel lifter.
