Edelbrock heads on a 340 with KB243 pistons

What do they recommend? And I missed a question earlier,yes they are RPM's. I got the heads new at the Mopar Nats last year for $1250, I got the guy to throw in a Victor intake(which I'll never use) I bought a performer RPM intake at another swap meet for $120, brand new. I have several cams laying around, I might go a little bigger on the cam but I don't want it too radical, maybe a 484/284
