I've sometimes found it helpful to keep them in a kitchen freezer overnight to make installation easier but if that doesn't work for you by all means use dry ice. Don't forget a block of wood or similar to protect the valve seat from an errant hammer blow.

If the installation is particularly difficult, you might consider running a correctly-sized reamer thru them after installation to insure a smooth internal bore concentric with the seat.
