Possible cam install

T67Power the material is like a thick paper however it is designed to withstand fuel, high heat, etc. all the thing that an intake gasket might encounter. Some silicone was used around the coolant passages. What is sad is that an exhaust manifold gasket that was made out of the "proper material" leaks out of the box and it cost me 4 times the amount of my intake gasket. some times making you own stuff turn out to be the best. In my case only time will tell.
