Removing the head will give you the most access to do a neat job of recovering with whatever product you choose.
On my Sov that's an easy job (two nuts) since the cold water supply is a flexible hose, but I've no idea if your '95 is similar.
Secure the nuts AWAY from the opening if you do that. You don't want to have to chase one or both down the hole...
