you would have lowwwwww compression ratio if you run them as 64cc with out having them milled or changin tha pistons.. sell tha whole motor & trans & make some coin..you can use tha serp setup...water pump & tha wheels with work ..depending on if they both are 5 lug 2wd..or there both 6 lug 4wd...it's not worth tha wrench time to do tha head swap
