Switching from WSM to 7mm-08

Will I need to switch firing pins? I just bought a completed bolthead for 308 family of cartridges from SSS. Also if I am going from DBM to internal magazine can i do that with an internal magazine box, spring and follower? Will there be anything else I need?

I switched from 300 WSM to 22.250 and did not have to switch firing pins. I did have to adjust the protrusion, which can be an adventure in itself if you've never done it before.

You can alwaays sell the extra parts.
