Advance the cam timing to +4 degrees with new timing gear chain set and offset keys or the timing gear sets with different slots for the key. .
Advance the ignition timing until you start to hear detonation and back off 2 degrees and use 93 octane not 91 octane all the time. The low compression of your 460 will not probably detonate until about 14 degrees initially if then. Have the distributor curved. there are still shops that do that since most hot rod engines are old iron. They can cure so that total ignition timing won't make it knock. They can retard timing as engine rpm goes up too.
