Thanks for the info guys. Im not sure the accuracy of the chart since these are on my 1965 galaxie with a 390 and im 99% positive its all original, but if you have actually measured several of these RapidRuss, then that sounds good enough for me to count as fact. Thanks for the response guys.

If you haven't stood over it since it rolled off the line, you can't be sure it's original.
Ford may have used those heads, as that is not unheard of and casting numbers don't change every year.
Or, the original engine may have had a burned valve or two somewhere along the way and the heads were exchanged vs. rebuilt.

Very true, hence the 1% doubt I have always heard these are fairly decent flowing heads for factory castings, and since the factory 1965 owners manual (which i have) says it came out with 10.2:1 compression, 300 hp, 427 ft. lbs., and was designed to run on 101 octane leaded fuel, it wouldnt suprise me if they where factory. But you are right, the car is 46 years old and i have only had it the last year and a half, so there is no way to be positive thats what they rolled out with.
