        which side of the gasket will go toward the head

        • As you can see the gasket is not symmetrical. When held up to your headers, it will have a clear fitment as there is only one way to line it up.

            Long tubes

            Installed them with pipes long tubes because it’s the same shape, added a little silicone for the best seal and they work great!

            Great quality

            Bought these for some headers I had purchased, they came quick and are built very well not flimsy like the last set I had gotten very good product, can’t go wrong with kooks.

            No leaks so far

            I bought these instead of Ford Racing gaskets since they were out of stock. So far they have not let the headers leak which is awesome. Just take your time cleaning and make sure these fit good and you won't have any problems.
