Valve springs

#1
I have the 212cc predator clone and recently installed the OldMiniBikes stage 4 hemi on my DB30, the kit doesn't come with upgraded valve springs. It has the mod 2 cam and I can't find any 22 lb springs to turn 7,000 rpms. It is floating the stock valves. Can someone point me in the right direction on where to get 22 lb springs. I found 18 lb but I would like some 22 lb springs.

Thanks guys, I wasn't sure if it I needed them unless I was running a more aggressive cam but 3x the agreement on them seems like I'll go ahead and get a set.

Ok kinda stupid question I've got.. Will I need to upgrade the spring retainers? The description says:

The "White" Spring. Use as intake spring when using stock intake valve and ARC DJ-1046 Spring retainer Use as Heavy spring for intake and exhaust when using our stainless (DJ-1121,22 and 26) valves Not recommended with stock retainers. For more info, download our spring rate chart here.
