That's the same Cam GM uses in their RamJet350 and HT383 Crate engines. I don't think it's a bad choice for what you plan to do with it. It's designed for Vortec Heads/Flow pattern so I'm not sure what will be the best choice with your Brodix Heads. A Cam Co. would be your best bet.
PS. The -8 Pro Head isn't a good choice for what you plan to do>> http://www.brodix.com/heads/-8.html
