What you have is an early set of 1969 Ram Air IV heads. The early heads had the entire casting number, 9796722, on the end port. You should see a casting letter/number combo just right of the center exhaust ports below the valve cover ridge. This is the date production code. The first letter is the month, A= January, B= February, etc.. The next two digits are the day of the month, 01 through 31. Finally, the last digit is the year; which for your heads should be a "9".

Hope that helps.
