intake leaking anti freeze

If it's coming out from under the intake I would guess that the head/intake water jackets are not sealed properly. Be careful because your probably getting antifreeze in your oil too if it's leaking on the inside.
Edelbrock intake instructions say to only use the rtv without the gaskets on each end. As far as torque values I am not sure but, You do have a sequence where you start at the center of the intake and work your way out to each end.
IMO I would try torqueing it down again and see if that works. I believe Edelbrock instructions also say to retorque after it gets hot. If that doesn't work I'd pull it and make sure they did the job right. I always put a light coat of rtv around the water ports on the intake gasket too.

Did you have any head milling work done?
