Chev SB 8mm Lightweight Valvetrain Conversion
Everything you need to assemble your own high performance heads.
Designed for better valve control and increased valve train stability. These lightweight conversions start with smaller 8mm valve stem. They feature inverted conical valve springs and small 1.055" diameter retainers for even more weight savings. Because of this reduction in weight you can use less spring pressure to handle more rpm and more aggressive cam profiles. Valves and valve locks are bead lock design for better clamping force. Perfect for occasional use at the strip, but durable for the street. Great for hydraulic/mechanical flat tappet or hydraulic roller cam applications.
