This is a image-based puzzler (not so good for radio) The mechanic in this image is adjusting the exhaust valve clearance. Question: [Where are the intake ports?](https://drive.google.com/file/d/1C6dYEriScnU1j9tOYLUtq0nc5rPTdS7t/view?usp=sharing) ---

In the head, which is not shown in the picture. Motor appears to be an F head engine. ![IMG_2768](https://global.discourse-cdn.com/cartalk/original/3X/7/f/7fde8802d47792e6b4c946bbfbf47272968ebd83.png) ---

On the other side of the engine? The intake valves aren’t installed yet. ---

I cannot identify this 4-cylinder engine but it is obvious that the intake manifold is in the head and with the carburetor installed on the head. Here is a photo of the 1964 Rambler American Flathead Six. The Carburetor is mounted directly to the head and the Head is ducted to provide the intake manifold for all 6-cylinders… ![six](https://global.discourse-cdn.com/cartalk/original/3X/1/6/169cf01fd197b49eb97b6f6e86e47ac91d68892a.jpeg) ---

The picture is, I believe, a Willys F head engine block. The intakes are in the head, which is not shown. The spark plugs in the head are above the exhaust ports shown in the picture. The carb mounts to intake on the other side. ---

It could also be a T head engine with the intake valves on the other side of the block. A flat head design with a cross flow features. Mercer maybe? I just noticed it is a six- 1926 Hudson F head? ---

I have found videos to show that the block is a Willys F Engine.

Yes, very well done. You and many others are correct it is an F head engine with the intake ports in the head. Here is the full video from a great YouTube channel. [Will THIS 134ci Willys Jeep Hurricane Engine Last ANOTHER 73 Years?](https://youtu.be/V0FwDjiHIO0?si=feb6hsijs-rkJFD3) ---

No George, “L” and “T” head engines, AKA flatheads both the intake and exhaust valves and ports are in the block.

Thanks still a little confused. Does the flathead “head” contain any valves? ---

I have a flathead engine I still use on occasion; it is on a lawn mower. ---

> [@George\_San\_Jose1](#): > > Does the flathead “head” contain any valves? Nope, valves in the block, on the same side, also known as an L head. Here’s an aftermarket head for a Ford: ![](https://global.discourse-cdn.com/cartalk/original/3X/d/e/de2c18bab2ad83b69b9625b71a6459895d6d66d8.png) If each one is on the opposite side it is called a T head. One in block one in head is an F head. ---

Ok, getting the picture now. the intake ports are on the same part that contains the intake valves, which might be the block or the head. . ---

> [@George\_San\_Jose1](#): > > Ok, getting the picture now. the intake ports are on the same part that contains the intake valves, which might be the block or the head. . George, The picture is not all that clear… As there are engines that have the intake valve in the head and the exhaust valve in the block… I am no expert, and it was only with this puzzle that I learned that fact today… The Hurricane Four engine featured an F-head (Intake Over Exhaust – “IOE”) cylinder head and the Willys F4-134 Hurricane F-head engine powered the M38A1 military Jeep in 1952. ![f head](https://global.discourse-cdn.com/cartalk/original/3X/f/d/fdaa4a858d562caed756ab3616360e3ba5a14a67.jpeg) There may be others, but like I wrote, I’m no expert, just a good Googler… ---

On a Flathead, the head itself does not have valves. The head has passages for coolant and holes for the spark plugs. The grey area on the pictures of the heads are the recesses for the valves. On air cooled engines, fins and plugs only. The F head from the original post has the exhaust valve and port in the block, the intake valve and port are in the head. ---

Yes. The intake manifold is incorporated in the head. ---

> [@Rod-Knox](#): > > intake manifold is incorporated in the head I don’t think I have ever seen an intake manifold incorporated into the head, the manifolds have always been bolted on to the head in OHV or OHC engines, bolted to the block in flatheads. There might have been some engines cast that way, I have just never seen one. ---

Yep, had one on my fire-breathing 170 cid Mustang! That’s one reason there are very few performance parts for that family of engines. [Next page](https://community.cartalk.com/t/pictoral-puzzler-where-are-the-intake-ports/198060.md?page=2)
