Motor got some water in it.It was a small amount.I am debating taking the heads off for a look.The motor is dated 10-72.Which head gasket should I use as it had the small plugs.Pretty sure it has the extra cooling passages.
Were small plug heads available in 72? Those heads are later 70's I believe, are you sure they are 346? I've only ever seen 452's with peanut plugs and the extra cooling passages.
