Bob I am emailing you a side view picture of my engine.

My 1957 block also has a line like that to the head. There is another plug behind the side cover plate by the distributor. PO said that he wasn't getting enough oil through that passage so he added the line. Maybe I got "a line"?

How can I test that passage to see if it is blocked? Maybe I have the wrong head gasket or installed backwards?

This topic has me worried about my new purchase.
