GTO 400 HO Engine Valves

Does enybody know were I can get for my 1968 GTO 400HO engine with # 16 head the intake and exhaust valves ??? They measure head diameter (by the service manual) Int. 2.06 and Ext. 1.72 . the rest is the same. I fund in Ferrea 2.11 and 1.77 but I dont know if they are to big. Central Virginia MS doesn't answer my emails. I don't know were else to look. There are a few photos of my original valves, but their measure is still different. Check the photos. Thanks for any help. P/n would be great.

2.11/1.77 is the correct valve size for those heads.

I bought the Ferrea valves for my #61 heads and my machine shop said they are the best. I got them from CV in Thomasville, NC. 1-877-781-8877 at a super price.
