I adhered the cork gasket to the head with #2 Permatex on my ‘59 235. I did not put any on the top, as I wanted to be able to remove the cover easily. It builds a little dam around the gasket area to help keep control the oil. No leaks!

The 235 only has four 1/4” bolts attaching the cover to the head, so it’s not much if any better than the two on top of your cover. In fact, it's real easy to overtighten the bolts, deforming the cover, causing leaks.
