How do I make Carb valve covers wor w/EFI

[87GT 306]

Got some motorsport Carb tall covers, they each have a breather hole. How do I make these work with my EFI setup. (I do have an intake spacer)

Put a non-breather cap in one side; and in the other put a non-breather cap along with a hose nipple. Connect the nipple to the nipple on the throttle body -- and leave your pcv valve hooked up as it is.

This will duplicate the sealed stock system.
