Confused newbee with a 273

I"ve owned enough 64/65 barracuda"s to know the headers offerd today are not worth the $ vs hp either find an old set of spitfires wich give you miminal differance in hp but breath a little better and give good sound. For any performance take your car to a perfessional pipe builder with a good reputation,as cosig said these are earley A bodies ,smaller engine compartments , or you have to get fenderwell headers. TTi will sell you dog turds and tell you there from ahorse just to make a sale. when its time mine will get made by a guy that builds perfessional show cars and done right without spending 900.00 from TTi for pipes that need to get remade. Burnywill charge me 1200.00 they will flow ,look good ,they will be garonteed , and nobody chopping other than cutting and remaking the crossmember will be done and they will have 2 1/2 collectors add hp and I am thinking of dumping them at the back of the doors . But to each his own. just my opinion
