Nope. At least not in your application.

There's a reason CJ heads have the 16-bolt pattern. You can't install bolts in all of the vertical positions. The only way they'd fit is if you left out some of the bolts. They are also intended to fit the higher CJ exhaust port. This means that the exhaust slams into about .25" of the manifold at the bottom. Admittedly, there's very little flow there but it's not something you'd want to do if you had a choice. Ford did just this on the big car engines using the low-port head and the earlier, unchanged, exhaust manifolds. In those applications, it was somewhat inconsequential.

Besides, and again, Ford log manifolds -even the CJ- are the pits.

If you want to use factory iron manifolds, pull the heads and get them drilled for the correct pattern and get the correct manifolds. Otherwise, leave the heads alone and get headers.
This thread, so far...
