Wossner Valves

[Leo991!]

Has anyone fitted Wossner valves? It states that they need to be fitted with uprated valve springs due to an altered collet height, I’m only running the standard 182 cams so I’m unsure if I can fit uprated springs (cat cams springs) to a standard camshaft?

Will they be to stiff? Or will they ‘wear’ the lobes on the cams??

Anyone shed any light!?????

Catcams springs are fine with stock cams. I run them in 2 of my f4r on stock cams no wear, the followers are roller rocker.

When fitting the springs will need to be shimmed to achieve the correct fitted height.

Any benefit to Wossner valves over Supertech valves? They don't need different springs.

Also 197 springs are uprated over the 182 ones.
