I have these Sanderson Big Block Chevy Headers that have never been used. Theses are in excellent condition. I had to sell my 396 to awhile ago. These will fit on many applications. You get an amazing fit compared to tube style headers. In plain steel these cost $490 & w/ the aluminized ceramic coating $660. I want $300 for mine. Buyer will pay for shipping. If you have any questions please contact me @ thadican70@yahoo.com or call/text days only please 831-970-1462. Jerry.
