1/2" spacer. It doesn't matter the size of the throttle openings with that manifold. It is not a maximum horsepower design. It was intended to balance thottle response with emissions satisfaction.

It is a bit restrictive if you want more then the 300hp it was intended to deliver An open plenum design makes more power across the board, The four port is for better throttle response with something like an automatic transmission in a heavier car,
