Vacuum Tube - 6L6GC, JJ Electronics

Will I have to rebias a 2002 59' Fender Bassman Reissue if I install a pair of these 6L6s?

With any retube, you may need to make adjustments to your amp depending on the type of bias it has. Your amp will either be fixed adjustable bias (has bias pot on the back of the amp) , Fixed non-adjustable bias (bias is fixed by a resistor in your amp), or cathode bias (self biasing no bias required). The manual for your amp should be able to tell you what type of bias you have. Rebiasing an amp is something that should be done by an experienced tech. Many amp manufactures setup their amps to accept "middle values" for tubes. You can request middle numbers when ordering. Keep in mind, this will not guarantee you will not have to rebias your amp.
