K Series Cylinder Head Bolts A111E6111S
It's a false economy to re-use your old cylinder head bolts; they may have stretched too much.
Spending an extra few pounds now can save many thousands on a complete rebuild.
All bolts stretch once tightened and the K Series head bolts are specifically designed to "stretch" but they have a finite lifespan. It is best to use new long bolts rather than to risk breakage or over stretching when rebuilding an engine or re-fitting a cylinder head after head gasket failure or upgrading.
