461 Heads

I finally pulled the valve cover off and checked the heads on my newly purchased 327, they are 461's, I forgot to see if they are X's or not. My question is, what are the specs on these heads, valve sizes, chamber sizes...I found a refernce, but it sad that the valve sizes are 2.02 and 1.60. Is this correct?

Thanks,
Randy

they are either 194/151, or 202/161's Randy. You'll have to mic. them to know for sure.
