Need some help on building a 383

I have the 383 at the machine shop now getting all cleaned up. I want to know what type of numbers i will see with keeping the stock stroke, 11:1 pistons, ported aluminum heads, and a nice beefy cam. Also should I stay with the stock stroke or should I go for a stroker kit? I like the extra cubes but is it reliable with the 496 kit? I have heard from some people that theres no problem with it and some people have said it puts to much stress on the block. I want to build a good amount of horsepower street engine. I would like to have about 500-550 to the crank so I dont loose so much to the wheels.

Thanks for you help!
