Slant six head

I bought my OS valves from Oregon cams when I had my cam out there for a regrind. As I remember they were a buck or 2 each cheaper than Hughes. I don't remember the brand of the valves they sent me. Might have been the SI brand, I've since heard may not be being made any more. Stock /6 length and stem diameter
So for a buck or two per valve are the Hughes valves better? I have a Hughes Stroker kit and am very happy with it. I would think for an extra 24.00 I would go with Hughes
