Learning Abt Internals

[SKY 34]

hi,

can sumone explain what is usually involved when changing internals?

besides the forged piston, head gasket and all other necesary gaskets...

why is it necessary to change oil pump. water pump?

usually the process involved machining the head, this means more cc to the car? also what does it mean to get the engine block blue printed?

requires as much info abt re-building..is it legal? can I get a permit for it...it's internal I suppose no one will know...but will be nice if I can get a permit..

thanks
