    I think you are guna need to replace and get manafold gaskets, because there is alot more surface on the manafold then on the headers. Plus most of the time your holes are are in a diffrent shape. My flowtech headers were round while my manafolds were more square shaped. You might be able to get away with the header gaskets, but they can lead to leaking which can cause a loss of power too.

    Tell you what I do... (and this is coming from a lot of racing experience.. just use RTV or hi Temp silicone and put it together, torque it to specs and go away for at least 24 hours, you'll never have to re-torque like with most gaskets, and it's much faster easier and more reliable
