I looked online, all the Edelbrock intakes i saw had place for the sending unit. You may need and adapter to get yours to fit, but the hole should be there in the water galley. What intake do you have?
There is no recess for the thermostat on the Edelbrocks, or even the stock manifolds. The recess is in the thermostat housing. A stock thermostat and housing works perfectly on all Edelbrock intakes (well, all the intakes made for fords that have the thermostat on the intake, anyway).
That's not stock, then. You'll need to get a stock or aftermarket thermostat housing, so that it has the recess in it. I just went out to my garage and looked at the stock 2v intake. The termostat mating area is machined flat as a pancake ... no recess. I've never actually seen an intake with the recess in it.
