VALVE COTTER SINGLE GROOVE(1 UNIT=2 HALVES)

New competition valve cotter, these are precision CNC machined from 4340.
These are made to RACE spec as the only current type available are not adequate for performance heads or valves. Do not take the risk-buy the best on this part.
All the early heads used the 2A11 cotters, noted by the wide slot in the valve. Current production race quality valves and most aftermarket valves, use the 88G549 keeper with a single narrow groove. Valve stems with 3 grooves on some A-Plus heads, use CAM6795 keepers. Order the correct cotters to go with the valves you will be using. Two halves equal one cotter for one valve, order 8 for 1 complete cylinder head.
