ok....so i have decided to get the kb107's for my 360. now its time to choose rings. Are the gapless rings worth the money? i found one that isnt too bad of a price but it is rated for street/stock. I plan on having about 350-400 hp by the time i'm done. they cannot be used for over 10.5 - 1 compression. the kb's should be under 10-1 i beleive. can anyone confirm this?
