Dura Ace 7700 crank is creaking
My main ride is 9 speed Dura Ace with the 7700 double crank. The bottom bracket is creaking so I have ordered a 105 BB to replace the Ultegra that is in there now.
Should I replace the crank bolts when doing the bottom bracket?
What is the torque value for those bolts?
Thanks!

I've never seen anybody recommend to change crank bolts unless they're damaged.
Your torque is 35 - 50 Nm according to the service instructions.

Keep those old octalink road cranks going! I have like 5 pairs of 7700 cranks, they are so beautiful.

I have 7410 cranks on one of my bikes and I started getting a creak a few years ago. It turned out that I hadn't had the cartridge BB out in ~9 years and some grease on those threads quieted things down.

Good looking crankset! I expect your old bolts will be fine unless you can see that they are buggered.

I had this happen with mine. Take the cranks off and grease the splines. Also remove all the chain ring bolts and grease them and reinstall to Torque specs.
No more "creaking".
