Cams w/o springs retainers

Im lookin to either drop some stage 1 or 2 cams into my b18b. Is it possible to dude stage 2 without springs and retainers? Or maybe they make a stage2 cam that doesnt require them?

It’s possible but I would not recommend it. Of course anything is possible! :rules:

Well like is there a certain restriction? like not over any rpm or something
