That is the way I was taught to do it as well. The guy that showed me how built sprint car and midget race car engines back in the 40’, 50’s and 60’s. He had a shop in Gasoline Alley in Patterson NJ

Then I use a little silicone on a screwdriver to put some on the end of the bottom seal when I put them together.  This is the way we did it in the tractor shop years ago.  However at that time we used 3M weatherstrip sealer..  It still works great too.
