Webb Cams
Elgin Cams
John Dougherty Cams
If you know what to ask for, these guys make the cams (great for custom stuff). Builders like Imagine are excellent sources because they have been there, done that (aka, specific Porsche experience and know what works for similar engine combinations).
In fact, I just ordered custom cams from Dougherty with specific specs on intake and exhaust timing, duration and lift - specific to my motor and its components. While the ECU is the brain to the engine, the cam is the heart - I would argue the most important mechanical part of the engine.
