is not hard if you got the right equipment.(tools) there's 2 ways for doing this in car and removing the entire cylinder head. you got to get the spring compressor that allows you to keep the cylinder head in the car , and you also going to need a way to keep the valves from falling into the cylinder when the valve keepers are removed.usually we use compressed air but if not available before removing the keepers tie the valve stem with some fishing wire(string etc). when your valves are secured. proceed to remove the seals.
I will add that its much harder with an overhead cam engine because the cam needs to come out. Its a pretty quick and easy job if you have rockers instead.
