Some quick update on the car.
I have Dynatech headers and DSE motor mounts on the car. The headers fit very well, but they hang way too low. In talking with Greg at Dynatech, and looking at photos of Ridetech's Velocity, which was used to develop the headers, it turned out that I had the mounts backwards. So I spent the last week lifting the motor up and flipped the mounts around.
DSE mounts I had installed initially.
The mounts flipped around.
Ground clearance before
After. The headers tuck up a bit more. I gained prob 1.5" of additional clearance, which what I needed.
The car is still on jack stands so I have not measured the ground clearance just yet.
