i guess the title says it all, but i'm looking for some opinions on the best aluminum heads for a 383 stroker buildup that i'm going to be starting within the next few weeks, any ideas?

 

i know a guy that has heads on a 383 that cost 3000$ for both. they added soooo much power. its a naturally aspirated 600 hp 383. no nos or s/c or turbo. they were edlebrocks i forget what kind but youll be able to tell. they are pretty expensive.
