Sorry bct. I made contact with the guy I sold it to. He sold it a couple of years ago to someone in Iowa for a stream liner project. Maybe it's possible he's a member here. BCT is still in search of a cross flow head.
The Iron Duke head is a crossflow design. Exhaust on one side and the intake on the other. Most inline heads have them on both sides of the head. Either design has pros and cons.
To Charlie stephens... My wife had a 69 chevy II nova Factory 153 4 cyl back in high school.. Car was so underpowered we did not feel safe driving it.. Strange coincidence?
