Upper engine components for classic British cars, covering cylinder heads, gasket sets, rocker assemblies, valve train components, camshafts and timing components. The upper engine encompasses the parts above the cylinder block deck, the cylinder head and everything mounted to or driven from it, and represents the area of an engine where wear, performance tuning and gasket-related repair work most commonly concentrate.
Cylinder Heads
Cylinder heads in original-pattern and stage-tuned configurations are stocked across the major British classic engine families. Reconditioned-exchange cylinder heads are supplied with valves, valve seats, valve guides and valve springs to original specification or to the agreed performance specification, pressure-tested and ready to fit. Stage II and stage III tuned heads, gas-flowed, with larger valves and modified combustion chamber profiles, are popular for performance applications.
Gasket Sets
Head gasket sets and full engine gasket sets are stocked across the major applications. Head gaskets are produced in modern multi-layer steel construction for many applications, with composite-and-metal gaskets remaining the original specification on selected engines. Always replace head bolts where modern torque-to-yield specifications apply.
Rocker Assemblies
Rocker shaft assemblies on overhead-valve British classic engines are typically pedestal-mounted shafts carrying rocker arms that operate the valves via pushrods. Rocker assemblies are stocked as complete reconditioned units across the major applications, alongside individual components, rockers, shafts, pedestals, pedestal bolts, springs and circlips, for piecemeal replacement.
Valve Train, Camshafts and Timing
Valves, valve springs, valve guides, valve oil seals, camshafts, cam followers (tappets), pushrods and timing components, timing chains, timing gears, tensioners and timing covers, are stocked across the major applications. Camshafts in original specification and in performance grinds are stocked for the popular applications, with attention paid to correct cam follower compatibility (original cast iron tappets versus modern alternatives) and to running-in protocols on new camshafts. The MGOC Spares British Classic Car Parts Upper Engine range encompasses cylinder heads, head gasket sets, full engine gasket sets, rocker assemblies, valves, valve springs, valve guides, camshafts, cam followers and timing components for the British classics we serve. MGOC Spares is constantly expanding our range for these non-MG British classic marques, and new lines are being added to this section regularly.
