HERE'S WHAT TO DO...take that 400, toss that cam you have into it, run whatever old junk heads are on it already, use that aluminum intake and 750 holley....and shoot the juice to it. Save your apparently limited engine building knowledge and a pile of bucks by just running a 150 hp nitrous kit on it, and have a pile of fun right up until you blow that rascal up. There's no cheaper HP than NOS, but it will definitely be a quick education. You'll get good at pulling the heads to replace head gaskets and draining milkshakes from the pan, and before long you'll know that old small block inside and out. But you'll be going fast, and cheaply- for a while! THEN, buy the Smokey Yunick book "How to Hotrod Small Block Chevy ENgines" and read it so you know something about what you want to build.If you're bound and determined to run cast iron heads, this book will tell you all you want to know, and even show you how to port 'em. BUT CNC and Aluminum changed the world, so I'd save the junk yard stuff for everything other than heads, because aftermarket aluminum is the way to go there. Do this only if you want to build something yourself- otherwise, buy a crate motor and DRIVE it,-spending time to sort the converter, gear and rear issues that have all been covered here ad nauseum, because until the bite is right it's just a nice motor on an engine stand ( we call 'em "coffe table motors").
