KB Hypereutectics are the only ones I would consider using.

For forgings, you can go with Speed Pro/Sealed Power, SRP, Ross, J&E, the list goes on. Note that some forgings are more suited for race applications in regards to material and ring choice. The Sealed Power/Speed Pro's have been around forever, and there are a few well-known issues you need to watch for such as dome to chamber interference.

If you wanted to step up to a high quality street-type forging, I would recommend Autotec pistons. They are a little more money, but they offer several nice features & options not offered on "off the shelf" components.

For a camshaft, I would need to know all the specifics of your build, and as I don't want to derail the OP's thread, please shoot me a PM or an email and we'll go from there.
