rah rah,
I went thru a similar situation. I had some heads rebuilt that were from a working engine that had been out of the car for about a year. When testing the lifters, I found that -all- of the intake lifters felt a bit spongy. Most of the exhaust valves were firm. I know the engine did not have any apparent lifter problems before storage. A possible explanation of this is the orientation of the lifters in the engine. The cup of the intake lifters is tilted downward, while the exhaust lifters are tilted upward. This might explain why the intake lifters leaked down more than the exhaust.
