Aluminum cylinder heads

You must be building two cars?? One moment you just want a 4bbl 318, no races, just a nice cruiser. Now you want USA aluminum heads? :poke: LOL
Ok, for your race car, you have edelbrock and trick flow on the lower end of the spectrum ... made in usa.
I just wanted to be able to explore my options for when I freshen up the 318. Magnum heads require a expensive magnum only intake and the 302 heads are usually cracked, so I'm trying to find out what I can / should do, I'll probably wind up rebuilding the factory heads.
