Stock valve spring FYI
I feel like I'm in a typing mood tonight.
Here's some info to put in your storage
A stock 400 assembled spring height is 1.820 or so.
But the exhaust is 1.650
It will coil bind at 1.130-1.150
So if you leave the required .050" that leaves very little to work with, as far as stock springs. .450" or less
You can tell what one of my jobs were today.
