How to take off an aluminum intake manifold

I have a 351w in my 82 bronco. I currently have a blown manifold gasket. I have taken everything off the manifold from carburetor to distributor. I have removed all the bolts the only place I am having a problem is how to pry the manifold off with out damaging it. I know aluminum can be soft and I don’t want to ruin my edelbrock manifold. Any help would be great.

hard to say, but I'd try a rubber mallet and tap the carb base. a few times, not hard
if that does not work just tapping around the flanges might loosen it...
when you replace the gasket use never seeze
