Re: Rust on Block Deck?
It appears some dampness was entering the cylinders. At this point, impossible to pin it down. It looks like not enough heat cycles, and miles driven occurred to present a problem. It could be short trips without time to burn off condensation. Can't really know for sure. I suggest a good quality copper gasket with liberal use of Permatex copper coat. Model A heads seem to seep moisture more than other early Ford's do. I ignore the sentiment of putting copper gaskets on dry. I get them good and stickey on both sides.
