New guy with M300 mini motorhome.
Here is showing the 318-3 closed chamber heads, with factory hardened seats. Your's probably has these on it.
Easy to tell from the outside as they will have the large Ford spark plugs in them.
Betting it's a 9.2:1 cr engine too, with free floating rods and a forged steel crank.
