New cylinder head for D1105 engine. Supplied bare.
Order your valves at the same as your cylinder head: Complete kit of 6 valves available at the special price of £40. Make your choice from the drop-down menu when you order.
The valve springs do weaken after a severe overheat and due to the fact you are replacing the cylinder head as it is probably cracked as a result of overheating consideration should be given to checking the springs - when the springs are removed simply line them up in a row and look at the heights and it will be obvious any defective springs will stand out . A good spring length should be in the region of 37mm and the poundage should be 25LB @ 31mm
