I've bored out the spring retainers to accept the peugeot 1.9D shims I'll be using. The reason for this is simple.
Jun camshafts are re-ground STD cam. To get greater lift, the base circle is reduced, meaning you need thicker shims.
My cams are 10.5 lift with a base circle of 30. The STD cams have a base circle of 32. This means me shims need to be roughly 1mm thicker than the Nissan ones. Although Jun sell the shims, they cost £7 each. The peugeot shims cost £2.50 each, thus a saving of £108. Also, my shims are an 'off the shelf' item. Nice
