It's not only how deep your valve can go but how long you can keep it there too..
If you're bound and determined to run a flat tappet cam ensure you remove your inner springs for break-in. Your cam lobes going away are a real and present danger at break-in .... and past break-in for that matter. The major engine builders are even plagued with this problem, hence the hydraulic/mechanical roller.
