If the umbrella seal doesn't go down any farther than that you have the wrong seals. The umbrella should fit over the valve guide and be able to push down and sit with the underside that fits thru the valve seated on top of the guide. Also, you don't put both the o-ring and umbrella seals on the same valve. Most shops put the umbrellas on the intake valves and the o-ring on the exhaust valves. There is also a special cover that fits over the valve tip for installing the umbrella seals so that the grooves don't scar or scratch the inside of the seal. It will shorten the life of them if its not used.
