Your throat opening (FB to CC) is way too large. For a 425 gal tank you should be ~288 sq.in.
Typically the top of the FB is the BP height if you're using a square shaped FB. I come up with a 13" high cut-out. That only leaves a couple inches to the lower grate because the tank is so long. Have you thought of shortening it?
No, but I've thought about just having 1 rack instead of 2I must have entered the wrong numbers. Sorry.
