I suggest waiting until you have the heads and valve covers as well as the timing cover, water pump and fan. This will allow you to set the engine to clear the radiator and also let you see how much firewall recess you may require. For the Ford Y-block I don't think the intake will interfere at the firewall area.
For overall appearance, you will find it to be best to keep the radiator in the original Model 'A' location (directly above the front crossmember) rather than moving it forward to clear the waterpump/fan assembly. More work to recess the firewall and set the engine to the rear, but will be much more satisfying in the end.
I like your rear axle setup.
The coil spring rear should give a good ride.
