If your problems are truly related to spring oiling, here is something that can be adapted without spending 5K, and it came from one of your threads:
I know who's engine that is....He used to frequent here a lot, then he sold that car. We talked about this, and I am not sure that would provide enough "spray" for a valve spring issue....might be good for push rod tips....I would have to try it. This is why I am shocked Indy or others do not make spray bar valve covers for a Hemi...
