Good mods to make torque in a 440

My question is whats a good cam and what heads will work well with these low comp. pistons( probably 8.5/1). I will be using some kind of dual plane intake but havnt decided which one yet. Any suggestions will be appreciated.

Use the crane 683801 cam and drop a performer RPM intake on top of it with a 1" HVH super sucker spacer under the carb. (spacer is worth 10-15ft/lbs)

Use the closed chamber heads
