Is it worth boring it?

ok so i am planning to have my cylinder ported. my question is, is it worth boring it to a 265? I would like to keep it legal to race with (if I ever decide to do that). it is currently about a 253cc. so how much would i notice the extra 12cc's? the swtup will basically be a TRX5 pipe and silencer, 38mm AS carb, uni filter with no lid, stock head with a thinner gasket, and a flowtek port job.

i wouldnt bore it if it doesn't need it...its always a nice thing to have some extra meat on those cylinder walls incase of a nasty lock up
