Everything looks pretty good to me. I think it should make a good 450 hp.
Depending on how much porting you do it could be more. If you assume 350 at the rear wheels, according to the calculator below you might catch a high 12.

I would not go into the runners. First, your camshaft is quite small and the lift quite low. Concentrating in the short side, bowl, and chamber, along with valve selection is where I'd suggest sticking to. You want flow improvments under .500 cfm. Runner hogging is not going to change much below this point. Obstructions around the valve will.

I'd also suggest not purchasing the camshaft until you have the heads flowed, ported and then reflowed. You may end up cutting back on the exhaust bias and even getting a bit more lift ground into the camshaft. The flow figures determine the camshaft. Syncing these two parts is how you wlll optimize the power. I'd also like to see bigger headers on the engine, 1 3/4. An 8000 RPM balancer SFI approved is not really worth the cost of the sticker. The same balancer, non SFI approved will save you some cash.
