I would look in to the holley systemaxII. I like this setup because it is a great bolt on package. The heads and intake are all gasket match and have been bowl blended . No spending four weeks playing with a dremel!!!
The packeage is about $2000( heads, intake, cam, chain, bolts) just add rockers(175) and go.
