None, they're the same valves. The exhaust valves were upgraded to Inconal for turbo apps. But from what I hear, all new exhaust valves are inconal.

yes, I used SBI brand turbo valves when I did my engine. 36 bucks apiece a year ago.

You can put 7.3 valves in a 6.9.
But do not use 6.9 valves in a 7.3.

The valve metal, inconnel, which is more heat resistant was the reason for swapping.
