As this was suppose to be about easiest to install, and I guess the old 340 high performance manifolds would be the easiest, but I have to agree with several on this post to the TTi headers. Sure they are expensive, but in most cases you get what you pay for. For me, an LA motor in an A-body, I'd go the manifolds, if one went with a B motor, I'd do the TTi headers. This is for the street, for the strip, yes headers, I agree.
