Regardless of the type, you should always have some method of plugging a leak 
or broken valve.  I have the soft Wood cones near each thru-hull as a safety 
matter.

David,
When I did the same job on my 75 25 Mk 1 many years ago, I simply unscrewed the 
gate valves from the through hulls and brought the valve with me to my marine 
retailer and matched the threads to reinstall the new valves..  Since most 
through hulls are bonded to the hull using some impenetrable goop like 3M 5200, 
you’ll risk damaging the laminate if you try to muscle the through hull out of 
the hull and I had no issues unscrewing the gate valve out of the through hull 
threads.  I was informed by folks much smarter than me, that gate valves can be 
very prone to failure and when they do fail, there’s no means of shutting the 
flow of water through the valve.  Rather than questioning, I took their advice 
and got all the gate valves out of the boat.
