Eric. I know you mentioned that they had the bigger valves installed and that the 206 were the preferred for the build. I thought the bigger valves would flow a little better? I was sending you my motor when I get the heads figured out

The bigger valves won't hurt, they just aren't necessarily needed at the level of build you're looking at.
