Difficult to install. And the thin gasket for the intake ports is not included. I used an aeroformed inlet gasket since I didn't have the flimsy thread-locking product that usually comes with these gaskets. RTV was included for corners and around water channels. Instead I used their red high temp product which I had on hand on a very warm day and when I was able to equalize it started to peel off, no leaks, used it under Edelbrock B4B, tried rubber end seals first and then I switched on the ends to RTV as I couldn't install all 12 screws with it. You shouldn't have any problems using the inlet, they are designed to be used with heads with AIR ports.
