    1978 Chrysler 85HP Powerhead Swap

    To guarantee to get it straight would involve to apply equal pressure divided across the head (impossible by hand) this is only good to clean/de-burr the surface of the head preventing from sanding dips in it. To "repair" a warped head it would have to be machined (if still possible)
