    I wouldn't mind picking up a spare set of heads for my 401, should I come across some. My question is are the 401 and 425 heads the same or interchangeable?

    If you get heads from 66 they have valve stem seals on the exhaust side.

    I have a nice set of heads from a 67XXX mile 1966 4 door Electra.
