The rear main cap side seals on Continental blocks were originally sealed with Permatex and string mixed together, always took awhile to get the grooves filled. I much prefer silicone BUT the cap and block must be completely clean and dry, any oil or grease and it will leak. There's a small bevel at the mating cap corners next to the block, I squirt silicone to fill the groove and make sure there's some at the bevel that comes out, then you know it's full.

The main bolts were a different size, if I remember right early gas and diesel blocks were 9/16 and later were 5/8.
