I have a pair of original style, non seam, valve covers for a 60 - 66 small block. Around the perimeter, gasket surface area, there are six very small holes. Approximately .060, evenly spaced two on each end and two in the middle. Are these holes supposed to be there? Are these for a particular year? They are on my 61, which I have owned since '75 and know the history since 1969. The holes are approximately in the corners and middle. Thanks for any ideas, comments.
