F 54 Z

Flint Michigan built engine
1954 year
Z = Passenger Car with manual transmission (mechanical lifters)

1954 car & truck mechanical-lifter 235s should have same valve train parts?
Yes, they are the same rocker arms.

Just to confuse things, the rocker-arm part numbers change in the 1957 parts book, but the same rockers were listed for 54-57.

If you are going for later rocker arms, wait to hear from others regarding compatibility. I'll bet that any 1954-and-later full set of 235 mechanical-lifter rocker-arms will work OK?
