The Cleveland 2V and 4V use different intake manifolds due to the difference in port sizes. Since the Power Port Cleveland 190 cylinder heads have 2V-style ports, Trick Flow elected to use an Edelbrock Performer RPM Air-Gap intake, which is an excellent way to upgrade a 2V Cleveland to a four-barrel carburetor. The Air-Gap features raised runners away from the lifter valley cover, creating an open space for air to flow through. This helps cool the incoming air and fuel, creating a denser mixture-and more power. The Performer Air-Gap has a 1,500-6,500 rpm operating range.
