After a long wait my Corvair heads were returned from Falcon Machine. Mark Petniunas did a fine job on them. They were cleaned, completely rebuilt, new exhaust valve rotators installed, low profile intake tubes welded on, spark plug hole number 6 welded and remachined and 4 new exhaust tubes installed. The engine will be reassembled when I gather a few more parts for it and attend a William Wynne Corvair college.
