James_R 3 Posted November 21, 2007 I'm looking for stiffer valve springs for the XU9 8v head I'd rather use OE items as they generally don't have issues and I've known of Kent items (in vauxhalls admittedly) to fail, I've seen petert mention some Datsun ones but can't find it in a search anywhere. Does anyone else know what I'm on about or am I going mad? thanks James Share this post Link to post Share on other sites
