The casting on the head reads "C6OE-C". I was told they have a 54.5 cc chamber. The original owner of the car gave me the flow bench paperwork. The heads flowed 220 cfm intake and 191 exhaust at .490 lift. I don't know if these numbers are any good. He told me that the numbers were on par with out the box TWISTED WEDGE heads.
I've looked everywhere and I can't find any info on a RHO motor from Ford. I was lucky that he gave me so much documentation, but what I really needed, I can't find
