The widest lash used on any CompCam solid roller is 0.028" intake hot, 0.030" exhaust hot. If I had a cam installed that didn't have a cam card with it, that's where I'd set them to start. Then I'd tighten 'em up a little at a time until I burned a valve, then back off a little. NO, NO, just kidding.
Get the number off the stick and call Comp.
