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

the 3 letter marking will be on the inside of the oil galley in the middle on each side..even if they dnot match up you can retrofit older blocks..those heads sound pretty good..probally made back in the day b4 aftermarket heads..back when j302s ruled and people were porting '69 351 heads
