Are they really needed?
Will be fitting some 225 cams soon so i need to change the valve springs before i put the head back on.Sbd say that you must use titanium valve tops with their springs but is that because they are the only ones that will fit?
Is it for extra strength because of the stronger springs or is it an
aid to help it rev by lightening the valve train..........or both?
The engine wont be reving that much higher than the 208 spec so i`m just looking to see if i can save a few £££
