CB Ultra wedge port heads?

[stretch]

Can someone please shed some light on exactly which valve springs are in CB's ultra wedge port heads.  They are listed as LS-1, but, I can't find a replacement on the CB website.  I have emailed CB a few times, but, have never got a response.  I have typed LS-1 springs into Google, but, it's confusing to say the least.  Any help is appreciated.

Hi, I thought I had the same problem with my heads but it turned out to be not springs. Anyway the info I got from Darren Krewenchuk was that manley part number 221426 should do the trick, or call CB.

They arent listed on their website, I think everything is migrating across to the VW650 springs.

Thanks Adrian.
