Tony,

One of David Vizard's books, How to Build & Modify Chevrolet Small-Block V-8 Cylinder Heads, has a lot of information on "old school" cast iron cylinder heads. The 186 casting is discussed at length and there were several flow tests included. Certainly worth picking up a copy for David Vizard's commentary if nothing else; the guy knows his stuff.

Hope this helps.

Regards,

Stan Falenski
