Wanted wanted intake/exhaust manifold 1972 fj40

[Big Guy]

If someone has a good used intake/exhaust manifold for sale please let me know. I have a very stock 1972fj40 & would like to avoid the header route if possible.

I have some NOS 2f exhaust+ intake manifolds, 550 USD, please PM me if you are interested.

I don't believe the 2f will fit my 1972 1f engine

I've got another one in MT, no cracks but the flapper won't move.

I have a couple of questions, first will a newer f2 intake/exhaust manifold fit my 1972 f1 engine & what is the purpose of the flapper. I don't think my 1972 has that, at least not that I know of. Any and all help is appreciated!
