Fixing Holley Power Valve Hiccups
There are two different styles of Holley power valves as well as two different gaskets. The open window design (left) requires the use of the standard round gasket. The power valve on the right uses a series of small holes, as opposed to the open-window style. The valve on the left requires a gasket with inside diameter “points,” which locate it on the valve. Through experience, we’ve discovered that the best plan is to use quality power valves from a company like Holley, or another reputable carburetor supplier. Stay away from the bargain-basement units. These cheaper power valves tend to fail much more often. View Related Article
