question about changing pistons

[hondapowerb16a2]

ive got a b16a2 with 21,000 miles on it and id like to get a bit more power n/a with some ctr pistons and some better cams. my question is, since it has low miles do i need to have any machine work done to the cylinder walls before putting in the new ctr pistons? also, if i stay the same size bore can i reuse my b16 rings if they are in good shape or should i just plan on new rings? not sure how all that works any insight would be apreciated. thanks

Well you are looking at about 10.8:1 or so if you keep your stock head gasket, you won't have to do anything if your motor only has 21000 miles on it just put them in, and spend the few extra dollars for the new rings you can find kits that they sell with it all (pistons & rings) together. Holy run-on sentence Batman.
