Yes, they will work. You have to use a 1275 Fel-pro gasket to fit the intake. Then, on the head, I took a 3/8 set screw (with thread sealant on them to hold them in place from going on down in the head) and run it down just below the surface. Then fill the rest of the hole up with silicone until it's level with the surface of the head and let it dry. After the silicone dries, put the intake on like you normally would. That's how I've done then in the past.
