I recently acquired a low-mileage 408 long block which currently utilizes a set of ETP small bore LS7 heads with a ported factory LS7 intake manifold. My question to you guys is, would a truck manifold style kit be out of the question because of the need of LS7 exhaust flanges? I believe something to do with the raised floor on the exhaust port. Please advise...

The holes are in the same location.

you have 3 basic configurations-

Stock LS1/2/6
LS3/L92 port is raised .060
LS7 is raised .125.

You should have no issue, just check the port match, and it may take some grinding.
