360 in a 66 Barracuda. Manifold question.

there are a few choices for headers depends on how much u would like to spend .. some are harder to install than others, but there are a pair by flowtech that are mid length and are simple to install, it doesnt plumb around stearing and simple to install i think they go for about 180 or so and have a nice thick flange so they dont leak...ceramic are always nice though much more costly though..

I don't think the Flowtech's will fit 1966 and older.
