It will with an adapter plate. I'd see if Holley shows something on their website or if Mr. Gasket makes something. I've put a Holley on a BBC spread bore intake so it shouldn't be any trouble to do the reverse.

yea Jimmy, I've been looking at what's on the market. The brand names all carry what I need. The Mr. Gasket piece looks to be my choice. Thanks....

Did you answer your own question up there?
That was neat!

Gaskets on both sides of the adaptor please!

The Mr. Gasket ones I've seen don't seal very well for the underside of the q-jet, and doesn't offer enough butterfly clearance underneath. After messaging Summit they recommended this one. I ordered it but haven't tried it yet. It looks like it will be close clearance for the butterflies, may have to work them over with a burr bit.
