I'm wonderin how much gaskets are and where I could find them by this Sunday to install my long tube headers for my gt. Any help would be awesome

 

Auto parts store. you will want to get aluminum gaskets (thats what comes with the headers) or you can get steel core gaskets

 

you can reuse the factory ones, i picked up some new ones from buyfordracing.com for about $20.

 

It's actually recommended by MANY to use the stock gaskets. When I had my LTs installed at American Racing Headers, one of the owners said unless you have a lot of miles then the stock ones are perfect (I had 3 or 4 thousand miles so I was good but I'm not sure what is considered a lot).

Good luck.
