144 170 200 heads

Are there replacement heads available without the fuel log cast on the head? If not looks like I'm back to my original plan of a v-8 swap.

Other than a stock one from Australia and a after market aluminum no. Both are pricey and hard to get.
You can have the log milled to accept a few different carb set ups. It is best to look for a large log head if your going this route.

Only the Australian ones called a 250 2V. American heads had a large log.

I FOUND THIS ON MUSTANG 360

Ford took the 200ci six's architecture and raised the block deck 1.66 inches in order to reach 250 ci for 1969. To achieve the extra 50 ci, Ford increased the stroke to 3.91 inches, which improved torque to 240 lb-ft. What made the 250 different from previous sixes was its larger main journal,bolt-on intake manifold[/color], and bellhousing/starter arrangement like a small-block V-8. It also had a new cylinder head for improved breathing and easier service. Available in the Mustang from '69 to '73, the 250 remained in production through 1976 in other Fords.

Take a look here. https://fordsix.com/ I'm thinking that's a typo or a article from Australia.
I have been running the little six engines for over 30 years. They are wonderful for gas mileage,durability and longevity. Very expensive to squeeze hp out of.

Good luck

I take it that the heads from the Argentinian Falcons don't fit? Those engines had removal intake manifolds also but were different to the Ozzie heads.

They did some cool stuff with the Ford six in Oz. Some history of the little six in all 3 places.

They do fit but are rarer than hens teeth.

Last I checked someone was working on getting the aluminum head back into production, would love to have one but way out of my budget.

250 head is the same, cast on log manifold.

Offenhauser intakes, like I have, are still available if you want to mess with multi-carbs. on my new head I am going to try and do my own modification and put 2 2-barrels on there because I am a glutton for punishment, besides I have the 3 singles now it would be too easy to leave it the same. :roll:

They can be made to fit, but (and this is coming from a 6 cylinder fanatic) you would be better served with a V8 swap than do the big 6, the weight is about the same and the conversion is easier and parts are cheaper. JMO.

I have a 2 V head on my 200 7 main bearing engine and it has been on that engine for 30 years. Plan to fit it to a 250 engine I have in the shed.

That is cool, I would love to find a head like that, that wouldn't cost a mint to get into the U.S., I understand they are getting to be quite rare down there as well.

A few years ago I considered getting a crossflow 6 that a place was importing but decided there would be issues when I needed parts, they are probably still available down there, a bit easier than the 2V I would think. I think I will stick with my flat top log conversion and the 2x2 barrel Ford Escort carbs, I have thought about making a piece I could cast in aluminum and attach similar to an Offenhauser intake.

Not familiar with the Escort carbs on a ford six, is there some advantage to running them?
The best luck I ever had running 2 carbs on a log head was acomplished by blocking the center off and welding two steel flanges between 2-3 and 4-5 for the carbs.
I dont remember why I didn't try three. Like the Holly carb off of the 240 for a single.

Mostly size and they are progressive 2 barrels so it would be like a long 4 barrel which should help with the fuel/air distribution.

Yep I would be spreading them out about the same, but again maybe wanting to try and make a cast piece, it is all experimental :roll:
