What do you mean by upper valve spring? You can move the valve spring retainer?! Nope, shouldn't be able too. You may have some serious damage. Bite the bullet and pull the head. Sounds like you have a broken valve. Way more than you bargained for.
The intake valve is the bigger one on 400's. The valves are fairly closely alligned with the ports.
The valve order on left side heads on 400's is E I E I E I E I, starting from the front.

Could be worse!
What's next? master cylinder, then fuel line, then brake line, then heater core, then blower motor, then radiator,...etc, etc.
These things are old and they weren't that good to begin with. Gotta expect trouble!
