I stand corrected...Hooker 2455's do fit square bodies. Pics

So I finally realized that BBC and SBC clam shells are different. Replaced the worn out rubber mounts with energy suspension inserts and used the 1/2 inch taller small block clam shells. This raised the engine enough that the 2455's fit like a glove. I had to clearance the flange for the taller head bolts, and I had to clearance the left side clam shell. Other than that they slid right in. The fit is close in some places, but still plenty of clearance. Here are some pictures of multiple angles.
