Help build a 408 stock block 5.9!

I am helping a friend come up with a 408 stroker motor plan that will make over 500 hp, and if the desire strikes down the road, capable of handling some mild boost, say a max of seven psi or less. My personal thoughts are it would be a good idea ro go forged crank, H beam rods, forged pistons.
So far my friend has a good 5.9 magnum core that runs. Some consideration to budget would be great.
In our talks, a moderately high revving combo needing a 3500 plus stall converter would be fine. This will be a hot street build with a couple trips to the reack possible.
We are looking for suggestions for heads, cam, compression and ignition.
