This is to confirm our conversation that you will fit the high rating valve springs EX.11888 to the exhaust valves only of a rattle complaint. We think that the valve bounce will be sufficiently high, possibly unaltered, and that the rattle may be greatly improved. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
