Product Description
Cylinder Head Assembly - Complete - Alloy High Port - TR4-4A Style Casting - 514748A
High Port aluminium cylinder head complete with hardened valve seats, valves & springs ready assembled. Suitable for unleaded fuel and pre-skimmed for immediate installation.
These heads feature thickened flanges and increased webbing between the spark plugs for improved strength.
Torque to 75lbs ft.
The LM25 aluminium cylinder head dissipates engine heat more effectively than the cast iron original and also saves a considerable amount of weight too, making it a great upgrade for performance applications.
The head will accept the original rocker assembly. We recommend you take the opportunity to service the rocker assembly at the same time.
Can be fitted as a direct replacement for TR3 from engine number TS13052, TR3A, TR4 & TR4A applications.
Can also be retro fitted to earlier cars (TR2 & TR3 to engine number TS13051) but will require the later inlet and exhaust manifolds to suit.
