The LS1 rocker arm is a popular performance upgrade among many engine enthusiasts. It provides increased valve lift and duration, as well as improved exhaust flow. The sequence of the LS1 rocker is fairly straightforward; it consists of three parts – intake side cylinder head, exhaust side cylinder head and the camshaft. On the intake side, the valve spring retainer rests on top of the rocker arm and keeps pressure on both valves. Then comes a pair of pushrods that connect to each individual valve stem inside their respective valve pockets in the cylinder head. Last but not least, a set of adjusting screws are placed at each end so you can adjust your engine’s timing for optimal performance. As long as everything is correctly adjusted and maintained regularly with oil changes, this setup should provide reliable service for many years to come!
