The F-Head 134 inline 4 was the standard engine in the CJ-5 andCJ-6 from their introduction until 1971. The F-Head was the onlyengine ever used in the CJ-3B. The engine also saw action instarting in the middle of 1950 in Willys Wagons and Willys Pickups.It was also used in FC trucks.
Willys MB/GPW: We won't lie, this Jeep model is our favorite.CJ2A/3A/B: This Jeep is the girl next-door.M38 & M38A1: The last of the military flat fenders and it's laterfull-figured version.Jeepster: You never had a chance.Shiny paint, chrome, white walls and a drop top. Jeep Wagon/Service Truck: Ralph Kramden's driver when he wasn't driving a bus.
The F-Head 134 uses a cast iron block and head with mechanicallifters and 3 main bearings. Two versions of the F-Head wereavailable most years, the output specifications are the samefor both, the compression is different. The intake valves arein the head, but the exhaust valves are in the block. Thevalve configuration makes the F-Head engine taller than the L-Headbecause the L-Head has the intake and exhaust valves in the block.
New engine compartments had to be designed to make room for thetaller engine. The CJ-5 and CJ-3B were designed with this enginein mind. It is fairly common to see a F-Head engine swapped intoa CJ-2A or CJ-3A. Normally a section of the hood is cut out tomake room for the carburetor.

There is a lot of confusion about the name of the F-Head engine.The F represents the valve configuration where one set of valvesis in the head and one is in the block. The 'F' in F-Head doesnot stand for 'Flat' nor does it stand for 'Ford'. Other makesof vehicles used flat head engines and some people think theF-Head stands for flat head. Another source of confusion isFord built some of their WWII GPWs with bolts with an 'F' on thehead so the parts could be distinguished from the Willys MB. Theyused F head bolts to build the GPW, but this is not related to theF-Head engine.
The main difference between different versions of the F-Head engineis the compression. The early F-Heads used between '50-'60 in WillysWagons, Willys Pickups, CJ-5s, CJ-3B, etc had a low compression F-Headstandard. The Willys Pickup only used this engine from '50-'56 andin '59.
