your quench is fine. why do you think the engine is under performing.
couple of things to look at... 1. ignition timing, where is it set? 2. headers too large 3. air fuel ratio? have you had this checked? 4. what springs in the secondaries? 5. what advance springs in the distributor
This!
provide the answers to these questions, and start doing some tuning. If you have the timing set at the factory specs, the motor won't run at it's potential.
