383 stroker

I have seen all the comments about low decks being a better fit in an A body so I'm considering a 383 stroked to 489ci. I have looked at 440 source and see they have a stroker kit for this and the aluminum stealth heads. Figured with these components along with a roller cam in the .550 lift, 240 duration at .050 range I could have a nice 500 horse A body that was fairly streetable. What do you think?? Has anybody used these parts before and what kind of results have you had??
