I was looking at Dart heads, Inconel and stainless valves last night, from 0.281-0.441" stem diameter, with and without sodium filling. I don't need the RPM of titanium valves, I found some heads with beryllium copper seats, I think. It seems to me if I have the power in a small block, I want to be able to use it. All the time. And a lighter small block with good valves might give similar continuous power to a run of the mill big block. But lighter. Especially if one went to aluminum heads, but even barring that, it is interesting to think about.
I am wondering if I burned a valve on the Yamaha F100 on the 20 footer. I ran it HARD this summer.
