That's not a do-it-yourselfer project because there's a lot more involved than just bolting a bunch of parts together. You'll need so many special tools that you'll never use again and there's a lot of critical measurements and clearances to check. You're better off buying what you want or having an engine machine shop do the work. We have a racing engine machine shop in my town and his products are not cheap. I worked there for two weeks as part of my instructor required continual training and I saw how complicated it is to get everything right.
If you still want to pursue this idea, look for a copy of the "Chevy Power" book. It's from the '80s; don't know if it's still in print. Once you see what is required, you can make an informed decision if you want to ruin your engine.
