But using stock LS3 heads and IM would improve HP more than reworking your LS2 heads. And you could also rework those heads for more power.

With a new cam, you will want new timing chain,lifters,dual springs and retainers,push rods and gasket set. I would also have the heads ported and polished with 3 angle valve job. Have your valves checked and polished (you can even machine the heads for larger valves). I would also change the intake for more flow and depending on cam bigger fuel injectors possibly. I would contact Lingenfelter for information on their cam packages.

Are you going to be doing the work or have it done? If having it done at a shop, I would get serveral quotes and just see what the shops say. I'm betting getting to 500 is going to be hard and expensive.
