340 Roller Cam/Lifter Issues.

I gotta wonder if plunger depth is the same? If not, then I don't see how they would work. There is no reason you shouldn't be running a full matched set. Even if plunger depth is the same. We all know about the oiling issues if the lifter comes up too high. And on the new ones it almost looks like the push rod makes contact with the lifter? Hard to say for sure from the pics. I wouldn't risk it.

Comes across like Comp trying to cheap out. Their paint wrecked their ****. They should do something more about it. In my mind at least.
