Chevy 250 Valve size?

Anyone know what the intake and exhaust sizes are for a Chevy in-line 6 cylinder 250, and a Chevy 292?

 

I had to refresh my memory by looking at my speed-pro catalog. On the 250, the vaves are 1.72/1.50 and I thought they were the same for a 292. The reason I am questioning it now is that they are listing the valves as being for the 230 and 250.
292 is not included in the heading. It may be because the 292 uses the larger stemmed exh. valve, I just can't remember.

 

There all the same, 1.72/1.5
