    Does look clean.
    Did you get the block and head machined before fitting the mls gasket? They prefer a super clean surface for the best seal

    Fire ring surface looks a bit suspect on cylinder 4 head side. (bottom left of the pic)
    Can see that piston is noticeably cleaner so has to be water getting in there through a crack or the gasket.

    Be better to have the head fly cut by a machine shop, should really have the block done too for a perfect job. Not 100% necessary so long as your careful cleaning it and dont dig in at all

    Head seems to be cut last rebuilt, and as long as its straight i wont machine it as closest chop is 400km away But will use a mild scotch brit and brake cleaner and try my best ;)

    Some Hylomor on the MLS gasket can help it seal

    Is the head flat?
    Bit concerning that the groove is so deep between the cylinders and not consistent all the way
