Just bought a 454! Build Suggestions?

[JacobSchni]

So i just bought a 454 iv for $300 minus carb and some of the pulley setup. Just waiting for the guy to pull it from his truck. Im trying to plan how i want to build this. I think im gonna bore it to a 468. dont really want to spend a fortune on it. Id like to try and stay in or under the 5 grand range for a total. What recommendations would you have for a build. Its gonna be a street build, i wanna run on pump gas. block casting #10069286, head casting #14092360. Not sure about the heads. hear that they aren't the best for power. wanna be making close to 600 hp/low 500 ft/lb (realistic for the price?)

truck its going in.
