There is a Ford 335 Cleveland Series Engine Forum, if you are
not already aware of, and I believe the address is:
www.network54.com/Hide/Forum/19419. They seem to be
strong believers in the Australian 2v heads for the street. I,
myself built a 400m with 4v quenced heads with spacer plates
and an Edelbrock torquer and 750 Holley combo. Haven't
been on the street in my Midstates yet as it is not quite finished.
Don't forget the Ford swap meet in Columbus on the 30th and
1st coming up. Lots of Cleveland experience and Australian
parts available.
