Single Spring, titanium ret, seat kit
Spring Pressure: BC1340 Seat: 1.300" @ 82 lbs / Open: 0.900" @ 188 lbs / Coil Bind: 0.810" (no machine work req)
Note: Machine work should not be required but you must verify spring seat BC2930 sits flush against the cylinder head.
2AZFE Stainless Steel Valves
BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel material to insure reliability with high boost and/or high rpm applications. The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber. Every valve is fully machined and features a swirl polished finish under the head.
34.5mm Intake (+.5mm head diameter)
30.0mm Exhaust (+.5mm head diameter)
2AZFE VALVE GUIDES
BC premium valves guides are made from Manganese Silicon Aluminum Bronze alloy and CNC machined to exacting tolerances. BC guides are resistant to cracking and corrosion, while reducing friction and insures high lubrication even at elevated engine temperatures and rpm's. The perfect replacement to worn or damaged guides and 100% compatible with BC's lineup of stainless steel valves.
