Titanium Valves Allowed in S/S?

If I were to build say a BBC, I would call Comp Cams. I believe they would tell me I need a 55mm camshaft in this engine because it would flex less than the standard camshaft because of the spring pressure I will be using. Then I would send the block to a machine shop to have the lifter bores machined to accept a Chrysler lifter because the std GM diameter lifters don't seem to have the life of the larger bores. A set of .165 pushrods are recommended for strength also. I would call T&D or Jesel for a rockershaft system because the old Crane rockers and a stud girdle just won't last. . Now I have all these special parts and machine work to prevent flex in my valvetrain but am not allow to use a slightly lighter valve of the same dimensions in those highly modified heads. That makes sense.

I have a friend who runs a 69 Chevelle with a 500ci motor and a stick. 3300lbs. He has run a Jerico transmission, and for many years run a paddle clutch with 2500lb pp. He has never broke a transmission in almost 15 years. How? He replaces the transmission EVERY year.
If Barton never broke a valve it may be because he replaces them at every rebuild-which is what 25 runs in those cars?

I'm the guy who refuses to put a clutchless transmission in his car because I feel it's takes away from what a SS car should be. But I'll put titanium valves in my engine in a heartbeat. Any guys that feel different, put a 8000 chip in your 2-step and push the gas petal to the floor and hold it there. Thats what a stick car does on the starting line.

I vote YES.
