Still loking for an intake manifold

[IcemanAK]

Does anyone know if they make an aftermarket intake manifold for a 78 cj7 with the 258 4.2l i6. I want to eliminate all emissions since my state dosent require it any longer. I have all of the stock intake and exhaust but i would like to run some headers and and a nice intake.

There are places that will take your current one and design another to fit. They trace the important areas so everything lines up, then cut out pieces with a CNC and bend pipes for it. Then they'll weld them or you can bring them in somewhere else to be welded. They'll do this at many metal fab. shops very inexpensively.
