I am a camshaft measuring crazy man. So for roller cams, I like a lifter tool with a ball on the end (wheel dia). The o-ring seal on the lifter bore is nice to hold it in place.

I actually made my own with a dia for Mopar.

Since you have a KB block with the double side bolts, I made a tool to press the caps on straight. It also removes them easily, but that is nothing special.
