Sure is possible. Using a pair of valve spring compressors available from our host, you can do valve stem seals and springs/retainers/spring-seats with the heads and cam carriers in place. Easiest if the engine is out on a stand with the exhaust and inlet manifolds removed. That way, if a valve drops in a bit, you can lift it using a finger through the exhaust/inlet port concerned. Otherwise, you can keep the valves up by using compressed air in the cylinder via the spark plug hole or just set the piston to top-dead-centre for the cylinder you are working on. Fiddly job but quite possible. Warn your friends and neighbours to expect the odd cuss.
