Aluminium Cylinder Heads - 1275cc

Alloy head casting with improved water jackets particularly around the exhaust ports and 12mm spark plug. By using the smaller spark plug it has been better positioned for cylinder burn. Out of the box the port gas flows as well as a well modified iron head. The valves are positioned slightly further apart giving the possibility of 38mm and 32mm valves being fitted. The standard head comes with 23cc chambers with plenty of scope of enlarging for turbo applications.The valve inserts give unleaded capability. Deck thickness gives plenty of scope for skimming (increasing C/R). When fitting an Aluminium head, you MUST run with 100% summer coolant which contains the correct inhibitors to prevent corrosion and electrolytic reaction.
