The friction plate in an uprated Exedy Organic are different to the standard versions, as is the clutch cover.
The Valeo one in the link wouldn't be recommended, nor would a standard Exedy organic friction plate.
Unfortunately the uprated friction plates are no longer available on their own.
At 350bhp you'll be wanting an uprated Exedy organic clutch kit to be assured of holding the power. Mine took a lot of drag abuse and they last very well.
This is the kit you would want:
