Delphi Hydraulic Lifters are the only choice when selecting Hydraulic Lifters for the Holden 6 Red and Blue engines
These Delphi lifters have the hardened pad on the camshaft face and are suitable with the correct valvetrain to operate up to 6500 rpm without the annoying tick found in some aftermarket lifters.
Anti pump lifters only work as anti pump when set with proper preload.
Others available for both Chevrolet Small and Big Block as well as the Holden V8 253, 304, 308, 5 litre engines.
A great product, I also stock Valve timing sets for various engines so please feel free to contact me with any of your performance enquires
