Efi to car pcv HELP !

I purchased an 89 town car efi engine as a cheap replacement for a 73 carbureted engine that plugged the sump and ate its rod bearings . Im swapping from efi to carb intake but the pcv passage at the back of the valley is exposed when the carb intake is installed. Im sure if it were left open it would pose a vaccum leak or an oil spraying mess . Any ideas ? Thanks for your help !
