Very good question. Been wondering the same myself. Since i run the aem ecu i'm not worried about the computer but would like to know the biggest cam those heads/valves can handle?
Well i have my heads off and they are with the machinist now. He called me the other day telling me i need better springs cause the factory springs were binding around .450. The cam im gonna use is the comp cams efi grind #34-255-5.

Wow. That sucks. I thought the stock springs would handle a bit more than that. I kind of want to go with a little bit more lift and duration than the 34-255-5.
