Competition Composite Head Gasket
The key component of this upgraded kit is the competition composite head gasket, providing an upgraded gasket option for A-Series engines where improved sealing performance is desired.
 
It is particularly suitable for:
Performance-oriented A-Series builds
Reconditioned engines
Cylinder-head upgrades
Fast-road applications
Engines undergoing a complete top-end overhaul
Owners wanting an upgraded alternative to a conventional replacement gasket
 
Upgraded Viton Valve Stem Seals
Unlike basic head sets using traditional early-type valve stem seals, this kit includes 8 upgraded Viton A-Plus-type stem seals.
 
Viton is well suited to the elevated temperatures and oil exposure encountered within an engine, making these seals an excellent upgrade during cylinder-head servicing or rebuilding.
 
HS2 & HS4 Carburettor Gaskets
The kit also provides a useful selection of gaskets for SU HS2 and HS4 carburettor installations, including air-cleaner-to-carburettor gaskets.
 
Because this is a universal kit covering several A-Series configurations, not every gasket supplied will necessarily be required for every engine.
 
Important Fitment Information
This kit covers 850, 948, 997, 998 and 1098cc A-Series engines, but many Classic Minis and Mokes have had engines, cylinder heads, carburettors and manifolds changed during their lifetime.
Always identify the actual engine and components fitted to the vehicle rather than relying solely on the vehicle's original year or model specification.
 
Installation Notes
Correct preparation is essential when installing any performance cylinder head gasket.
The cylinder head and engine block mating surfaces should be thoroughly cleaned and inspected, and the cylinder head should be checked for flatness and damage before installation.
Always follow the appropriate A-Series cylinder-head tightening sequence and torque specifications for the particular engine configuration.
