Comp 987 springs.... I called one of the leading LS1 cylinder head vendors last week and was told that the Comp 987s are not a very good spring. After looking on the Comp web site their catalog said that the 987s were only recommended to a .500" lift cam. Any input?

Re: Comp 987 springs.... wait a minute! My SII heads came with 987's double valve springs. I was told that there good up to .630 lift. As they better, becuase my cam is 228/236 .571 .602 111LSA
