well if ur lookin to rabuild just have some head work done and get some flattop pistons
but i fnot u could just buy some new heads with a smaller combustion chamber
and if u dont want to spend that money u could even cheap out and just take the heads and have a valve job done and have them mill the heads down a few ccs
