Head Numbers

The cylinder head numbers on my sbc are 3890462. Any charts I've seen say they are 2.02 valves with 64 cc chambers. I tried measuring the valves without removing them and they appear to be 1.94. Were both valve sizes available for these heads and if so are they indeed 64 cc chambers?
Thanks
