Len....I hate to say this but you said to speak up!
The locking plates and screws for the IP valves in your picture still show the original factory yellow paint streak on them. If thoughs are the original IP delivery valve "O" Rings in there you might as well change them out now while you have the manifold off. If not they will probably start leaking over the summer and you will have to pull it again. I am sure you'll want to spend your Saturdays at the beach than doing that job all over again........
Cheers
