John;
I ended up not installing the heat shield as I found I do not need it. I built a live test stand and ran my engine about ten hours before installing it in the car. I have now put around 8000 miles on my car. Longest trip was 1250 miles in 3 days. I just returned from two weeks on the road and used my car as my daily driver. It neverlet me down and ran great the entire trip.
