It depends more on the lobe design from what I understand. If you have a very aggressive ramp rate. The lifter and pushrod can lose contact with the cam lobe. Its all about how the valvetrain is designed as a whole.

Exactly, .550 and up cams have more aggressive ramp rates, more aggressive ramp rates need more spring pressure, run more spring pressure you need a lifter that can handle it, which means you need a pushrod that can handle it.
So either go with LS7 everything. Cam, lifters, pushrods and valve springs, or, use data supplied from cam specs and build accordingly. If you have a lifter failure, you cannot just pop the intake off like with a SBF or SBC.
