Thanks Jerry. No valve seats involved unless there is another crack that I don't know about. Probably should have it magnafluxed to find out for sure. It does go into the water jacket as best I can tell. I can stick my finger and feel what appears to be a crack in there just opposite the head surface. One fellow at a machine shop mentioned stitching. Will probably take the head to him and get a read on it next week. The engine has all new gaskets on it and is painted so it may have been totally rebuilt. I wonder if new head bolts are available for it. Old bolts have, in my experience, led to blown head gaskets due to their elastacity being compromised. Allen
