I assume you've read my book a couple of times?

If not you might start there. I don't see anything wrong with your plan as long as the heads are okay. I don't have any experience with those heads and I'd never use them myself but to each his own. For a street car I'd use Trick Flow 240 heads on an engine that size. The cam doesn't have to be very big to be effective if the heads are any good. With the TF240 heads I'd use a hyd roller cam with duration around 240@050. If you don't already own a carb or distributor then I'd recommend a Holley Sniper and Hyperspark setup. The Sniper will work better than a carb on the street once you get it dialed in.
