Vortec head studs???

I have the Vortec heads from Scoggin-Dickie which have been machined for a .550 lift cam. However, it has the push in style studs. What do you guys feel a safe max lift would be for these heads as is before replacing pushin studs with screw in type? Currently running a Comp Magnum 280H, .480/.480 lift. I want to go to a solid .501/.510 lift cam.

If the cam I`m using is over .500 lift, I go screw in.

I'm going screw-in for mine at .477 lift just to be safe. It will be in a boat, so it will see a lot of 5000 rpm. I use a sorta expensive shop, but they want $80 for the machine work, and about another $35 for the studs. I can have it done for $60 at another shop but I've had some questionable stuff from them. (just so you know what to expect price-wise)
