I am going to get copper header gaskets but i wasn't sure which ones I should get. The Flowtech headers that I am getting only have 1.5" primaries and I wasn't sure if regular header gaskets weren't to big for them. There are plenty of header gaskets out there but none say what size header they are for. Does that not matter? I know I need to get round port..right?

 

Round yes, as far as the size, just order the one for SBC.

 

Thanks Mark,

Now if I could only decide to keep my cat or not.

 

Get rid of the cat. It makes it sound and perform better.
