I recall performing this test once. My understanding is to simply squirt an air nozzle into each port, not actually pressurize the port. Like you mention, with enough pressure, the valve will open.
So, I think you are probably good on the valves. You could put the engine back together and go forward. If your oil usage was on the high side, guides and seals would be advised first.

Was that an unrealistically high pressure to expect them to seal (backwards) against? Should I put it back together and see how poorly it runs? Anyone want to sell me a complete, usable cylinder head instead? -Joe -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected]
