If you indeed are racing go for either the Aluminum retainers or if budget
will allow there are titanium ones available. You get into the lighter valve
train is better for higher speeds. springs are your choice - but as you are
using the higher ratio keep in mind some of the higher lift cams coupled with
the 1.5:1 rocker ratio can cause valve crush (let's not go into how I know -
just suffice it to say something will give - in my case it was the rocker arm
that snapped) so check it out. MiniSpares (London) sells a set of springs
just for this problem (so does MiniMania - Calif. at twice the price)
