Your original post did not say you were installing a big block. I do not know of any headers that will work in these trucks with a big block, with the engine in the original location and a manual trans. It is possible that a set of big block block huggers would work, but I don't know if they will clear the motor mounts and crossmember. Another option would be to change your motor mount brackets to a set of '68-'71 big block brackets and mounts. Then you should be able to use a set of '68-'71 big block headers. But you will likely have to still modify your original clutch linkage, or use some of the '68-'71 pieces.

If I end up putting a 454 in my '66 C30 with a SM465, I will be converting to a hydraulic clutch. That will be much easier. Of course if you were running a auto trans, there is no problem at all with headers, just a little trimming of the top flange of the frame.
