360 Advice Needed - Autocross / Street Engine Build

I've been running similar numbers in CamQuest, and it looks like in these flow rates, the manifolds are costing like 40-50 lb*ft across most the rpm range.

@ AutoXcuda, how do you have any ground clearance left with it low and the headers underneath? Even the TTI's look like they hang down low compared to the rest of the car.

Shortie headers with a factory looking heat shield may be my next best option.
Again, it doesn't need to be OEM mopar, but my goal is that is look like it "could" have come from a factory like that.

A bit of a different type sleeper build... :)
