I know rev makes titanium valves, but I believe you also have to run a special seat, I know TEA made a set of Ls1 heads with titanium valves

You're right; they are stronger and lighter than regular valves, but their high price isn't usually enough to outweight the benefits to most. If they came down in price, more would using them.

Ti valves are expensive and are considered a race only valve, they are subject to heat cycling so have a short life span, also you must use a beryllium seat as a standard seats hardness can damage a Ti valve.
they are lighter so absorb/use less energy to move but are not good for street use

There are several manufacturers of titanium valves a couple already mentioned - Rev and Ferrea. Also, Del West, Manley, Brodix, and Xceldyne. Xceldyne is sold only through CV Products to the best of my knowledge. Any of the sponsors, myself included can purchase from the above companies.

Titanium has a density about 60% that of steel. Therefore an exact duplicate of a steel valve in titanium will weigh 60% of what the steel valve weighs. Anything you can do to reduce the weight of the valve, spring, retainer, locks will help keep the valve train stable (out of valve float) at high revs.

Titanium is used in racing engines only. It is a poor bearing material in that it tends to gall up. The valve stems are usually plasma moly coated to keep them free in the guides. Connecting rods have the big end sides coated to keep the rods from welding themselves together.

Titanium needs a soft valve seat - beryllium copper to keep the valve from wearing away. Even then a lot of guys are now coating the valves with a DLC coating to make them more wear resistant.

Titanium valves are a lot more expensive than steel but are a necessity for most racing applications.

Too much to justify using them in a regular street motor.

Thanks, this would not be for Street application but for a high reving stroker.
Just observing the possibilities.

How much power gain would they provide over regular valves?

It's not just a straight forward power gain you would get by using them. If you have valve float, there are 3 ways you can fix it -
1. Don't rev it that high
2. increase spring tension
3. lighten the valve/retainer/rocker tip
If you have a setup that wants to make more power and rev higher but can't because of float, this is what you would do. For 1600 bucks, I'd make a different cam choice, cuz it just isn't worth the dinero for most of the people at our level.
