My 340 in my 66 developed issues :-(

Between the restriction in my exhaust, hearing what you guys have to say, and among other things I think the cam I have wasn't allowed to do its thing. It did pull hard but it seemed to loose steam.. Anyhow, I decided to not swap the cam and use the one I have.

So I worked all night at my normal job then got home, collected my heads and went off to the machine shop.. I am very fortunate to have a true "speed shop/machine shop" so close to home. The owner is a hell of a guy and I've known him for ten years or so.
So, I am getting my heads gone through, ordered a new intake (Edelbrock 7576 RPM air gap), ordered new wires and a MSD coil, and some gaskets..

I am having a hell of a time finding headers! It seems the only way I can keep my colum shift with my 727 is if I use hooker headers and cut holes in my inner fender wells to do it. It's such a nice car I hate to do that! I'd really like some feedback in this area..ie, pictures from someone who's done it, confirmation it will be alright and it's the right thing to do...I need a little push is the bottom line... No matter what I don't want to cut a hole in the floor and install a floor shifter!!
