Depends. My setup would collapse the HR lifters even with the light checking springs. The straub technique doesn't require rolling the motor through with a pushrod. However when you do roll it through to look for the tip wipe, the lifter was wanting to collapse. I used a set of washers on the adj pushrod locknut to hit the lifter body to keep it from collapsing. There is a margin of error, but not much if you do it right.

My wipe pattern was just outboard of the center, but since I'm using longer valves, its to be expected. Longer valve moves the contact patch outboard of center, since the valve is angled toward the rocker stud.
