Yes, titanium valves were available in Cleveland sizes and are regularly used by racing teams. They don't negate the need for stiff valve springs, but they allow more rpm. As you might imagine, they are expensive. They are also tough on valve seats. I do not think they are readily available in Cleveland sizes any longer, but I do see them come up occasionally on e-bay & at swap meets. Modern Ford race heads use valves with smaller heads and in some applications longer stems, the Cleveland size stuff just isn't in demand by race teams any longer.

Stainless steel is the best material for most street engines. The caveat is to make sure the valve is a "one piece" design, if so, the manufacturer will specify "one piece" in their description of the valve. Two piece valves are known to come apart under hard use, and engines really don't tolerate a loose valve head banging around inside a cylinder very well!
