how to make 360 more torque

I already Have a 8 3/4 rearend with 3.23 gears Im putting in once i have the 360 finished. Its a factory 4bbl and he gave me free long tube headers with em as well. The only thing I'm missing is the 2.5 exhaust. Im thinking about putting a 340 Intake on it with a holley carb and a msd dist. I was also debating on putting the edlebrock timing chain. also I'm thinking about putting J or x heads on them what do you think?

A 340 intake would be great for a slightly warmed 360. Just don't skimp on the timing set-billet gears are best because the gear faces don't recede as the surfaces harden (they're already hardened). Either set of heads will do fine...just ensure serviceability...are they in better shape than the heads currently on the engine?
