There are tools to do just that. Doing one cylinder at a time, you remove a spark plug and install a quick disconnect air fitting in its place. Connect your shop air compressor line to it and maintain air pressure, 100 psi is good. The air pressure will hold the valve in place during this procedure. Now you will need the proper tool to compress the valve spring and remove the retainers (keys) then the valve spring. Remove the old valve seal and replace with a new one, then reverse procedure to install spring and keys. Your local auto parts store should have the tools you need for sale or rent.
