Don't get confused by some of the terminology that we've used. What Samwise called "double hump" heads, and Chevyasylum called "powerpack" heads, and I called "202" heads are all the same thing. Asylum suggested you get a good book on hot rodding small block chevies, and that is a GREAT idea. Not only will it put detailed info at your finger tips, it will also help you learn the vocabulary.
