    Got a seized 1980 xj650, found some pistons and head from eBay from a 1982 one for a decent deal, will it fit? I heard the 1982+ xj are different from the 80-81 ones

    The part numbers are the same so there's a good chance that the pistons are the same. Have a look at the link i've posted and you decide. If it was me, i'd go for them. The 1983 650 Maxim look like they are different though.
    Yamaha XJ650 parts: order genuine spare parts online at CMSNL CMSNL are the European distributors for all Japanese bikes. The American versions are usually the same.

    I found 4 pistons and a head all together for $120, appears to cheaper than shimming
