Complete IDA mani, or DOCE adapter from RB?

Hey all, which manifold would work better with two 50mm TB's? Keep in mind this would be for a N/A street car, shooting for 170hp on stock ports.
I am still going to build a turbo, but I want to mess with an N/A for a while.

With intake runners, shorter ones have higher the potential peak power at the expense of some bottom-end, while longer ones boost torque through the rev range but don't make as much peak power.

So the shorter runners of the IDA manifold will give more power, the longer runners of the DCOE manifold will give more torque. It's your choice, but if you're going turbo later, the IDA might be the better choice.
