which heads for a 408ci?

Interesting thread. My own opinion... Edelbrocks out of the box wont do it. A set of pro ported Edelbrocks will. You can port these yourself if you've never doneit. Not without a lot of practice you dont have yet. A set of prop ported edelbrocks will cost just under what the 360-1 Indys do, and wont flow as well as the Indy's could. I would buy a set of Indys and start fdrom a better place. Hughe's heads are the Engine Quest Magnums, and you will not find rocker gear to take that much abuse unles you spend some bigger money. It's not a question of a few chevy springs and you're good. At least not unless Hughes is doing more than I think they are. I dont know for sure.

600hp aint "a big deal"? That's funny...
