    Valve spring retainers difference?

    Does anyone know the actual valve spring outside diameter?

    What are the differences between the Les Cooke and the Riva valve spring retainers?
    Is one thicker to put more pressure on the springs to prevent valve float?

    What is the lock angle on the retainers?
    So many speed shops sell the Titanium retainers at such a better price than Riva,
    thanks,

    I guess the best way is to take a 4 tec titanium retainer and send it in and have them match it up,

    Both the Riva and Les Cooke retainers are lighter than stock and they both put more pressure on the springs. The Riva retainers are 100% Ti though and their kit comes with a set of rocker shaft bolts of which you will need. Not such a bad deal especially after you factor in the 10% discount with the greenhulk coupon code when you shop in this forums online store
