exhaust crossover

Has anyone put brass plugs in the back of the heads at the exhaust crossover. Mine leak, I fix pretty soon the leak is back PITA. will it affect my driveability. The crossover goes from the back of one head to the back of the other with a big valve at the center that goes to the smog pump. 84 F250 351w feedback carb EEC-IV

Plug the holes in the back of your cylinder heads when removing the exhaust crossover tube. Comes with 2 plugs and Loctite. Hex head makes installation easy when the engine is still in the vehicle.

the holes are threaded, I think a 5/8 bolt will fit. You can also cut the ends off of the crossover pipe and bolt them on backwards wich will cover the hole in the head
