Piecing together photos with notes from work orders, I assume they did the following:
1 - Fabricated intake manifold spacers from 6061-T6 billet aluminum to mount intake correctly with Blue Thunder heads.
2 - Port spacers to match heads and Edelbrock dual plane manifold.
3 - Port match Ford Motorsport “Yates” style single plane intake manifold for A – B intake power comparison.
