68 KAT is going to have a lot of mechanical work performed over the winter. One of the ideas I am kicking around is to replace the stock cast iron exhaust manifolds with some aftermarket headers. The last time I drove her (put in the leak-free Demon 625 carb) she had a definate increase in back pressure (blew the pass. side exhaust donut) and power.
So, does anyone have any big block header suggestions?
