I'm more worried about reliability. Are aftermarket camshfts pretty safe?

Depends on the aggressiveness of the cams, the jun cams are not aggressive so they are realiable

It's not the cam itself you have to worry about. It's the valve springs and retainers / push rods. The cam works by opening the valve more, putting more stress on the valve train.

I haven't looked in to this VQ motor enough yet to know how the valve train is laid out, but when I did the cam in my Challenger we did upgraded valve springs, retainers, and locks.

Which is the right way to do this, but those of us advocating that path were not taken into account.
