PRESSURE TORQUE PLATE
For those who don’t have a pressure tester, torque plates work great. Use along with homemade block off plates for the other holes and I use expandable rubber core plugs to seal up the block. I use them in cylinder heads as well. Just have a selection of threaded rods and wing nuts to clamp it down quickly. A head gasket will seal them right up if you don’t want to make rubber gaskets.
