Looks like the heads are off the motor.
The valve sized should be (obviously) smaller on the 304 head. |

It would run fine and not even be noticeable unless you are pushing RPM.
Until the flow of intake and exhaust become unbalanced (i.e. compression) it would run like a charm, guessing 4200 RPM based on displacement and valve size. A detailed calculation knowing carburetor, intake and exhaust would be required to provide more then a guess. I doubt that is required as you will likely put on matching heads for rebuild. Factory oops! |

Probably not a factory goof. Probably needed a head and they put on what they had. Our Forum member is in Norway.

A matching set of 360 / 401 heads will be a good idea.
If your budget allows get a set of Eddelbrocks. |

Just see if you can locate a single 360 head with the same casting number. That's really all you need! Of course some of the Jeep guys run 304 heads on rock crawlers as they produce a slight increase in torque at low rpm, and they hardly ever run over 4000 rpm.
