Welcome to Team Camaro! As Nantooch said, it's all about what your intentions (and budget) is for your car. There are a lot of variables that go into picking a set of cylinder heads.
In the entry level ($500.00 to $1,000) cast iron performance head market, you have names like the GM Vortecs, Dart Iron Eagles, Pro Toplines, and World SR Torquer's come to mind. And then there are aluminum heads....(Starting in the upper $900's range and up,up,up, [img]smile.gif[/img] ) There are pros and cons to each. For example, the GM Vortecs are an outstanding high performance and budget priced cylinder head. BUT, they require a special Vortec style intake manifold, center bolt valve covers, self aligning rocker arms and unless modified,can only handle about .465~.475" lift cams in stock form.
I personally will likely end up with a set of 180cc Dart Iron Eagles or 180cc Pro Toplines because they meet my performance goals, flow well, look basically stock, and are compatible with my stock A/C setup.
Just post what your goals and budget are, and the guys here can get you pointed in the right direction.
