Lightweight valves sources for LS1?

Can anyone recommend where to obtain stock size 2.00/1.55 valves for an LS1 but lightweight units?

A lot of the big valve companies like Manley and Ferrea make custom valves. The only lightweight valves that are worth getting will be titanium.

I have Ferrea hollow shaft valves on my intakes. They are ~30% lighter. t does make a difference.

You can also contact some of the vendors here who do heads, a lot of times they upsize the 243 casting valves and may have a set of Z06 lightweight valves available for sale. I found a set with a vendor last year.
