To truly optimize the engine and take advantage of the heads, you need to upgrade the cam. But, according to my machinist, he said 320 ish is common with an upgrade like this. I'd love to see actual numbers from a dyno though.

Well, dropped off the block to the machinist. He said that I need to go .030 over, because of some cylinder wall scoring. Looks like the pocket is already getting drained!!
