Replacing pistons help!?

If I replace the pistons in my block (b18a), would I need to rebuild the block?

I guess you wouldn’t NEED to but you have to take it all apart so why not? Usually just replacing pistons and rings seals the compression up so much the added pressure finishes off whats left off the motor and rods or mains start knocking sooner than if you would have just left the motor alone
