Rover SD1 V8 Head Gaskets
Composite head gaskets are thicker than standard tin gaskets and will therefore lower the engine's compression ratio. Ideal for correcting compression ratio when heads/block faces have been skimmed. (Not applicable 1995 on).
Approximate gasket thicknesses are as follows:
Typical effect on compression ratio:
- Standard (tin) gaskets - 0.5mm
- Composite gaskets - 1.2mm
- Standard (tin) gaskets - 3cc
- Composite gaskets - 10cc
