These pistons feature a domed head with 0.125\" relief for two valves, suitable for high-performance applications like the L79\/350HP variants. The set includes eight pistons and moly rings, with a 4.030\" bore size at +.030\" overbore, a 3.250\" stroke compatibility, and 5\/64\" 5\/64\" 3\/16\" ring grooves.
