Camshaft suggestions

I would do two things. 1. Pull the heads and install 2.02 intake valves and hardened exhaust seats. 2. Buy a Comp Cams Extreme Energy 268 cam. My 340 has J heads with 2.02 intakes, Edelbrock Air Gap, headers and the Extreme Energy 268 cam kit (cam, lifters and springs). It's good for 375 HP. Send me a PM with an Email and I'll send you a video of how it sounds.
