I'd be more worried about simply having not enough compression. 8.2 isn't terrible, but matching it with a Voodoo cam (219/227 duration IIRC) won't make any orgasms happen.
With a moderate mismatch like that, quench isn't your biggest issue. Bring that compression up to 9.5 or so and then you can start on the finer points like quench.
