How do the titanium valves hold up in the marine application? Are you using them for both intake and exhaust?
My 1.90" Inconel exhaust valves are as heavy as my 2.4" SS intakes. Would love to lighten the weight but I always thought Titanium is for drag motors.

I have used Ti. valves in a pile of drag motors back in my drag racing days, they where incredibly light, but, tended to be hard on valve seats, they take INCREDIBLE amounts of heat and are lighter than Inconel, but, unless you are spinning the motor to insane rpm levels I wouldn't recommend them in a boat, unless its a drag boat and/or you have a bottomless bank account and alot of free time for maintainance.
Something else I have found out [first hand] is you DONT want to ever "backfire" the motor, as strong and light as those valves are you would be shocked at how fast they "tulip" if you burp the motor.
I guess what it comes down to is that [99% of the time] there are better ways to waste your money.
Just my Thoughts!
