I'd like to help, mopowers. I think this has been stated in other threads for ya, not sure. Factory retainers will work just fine (though I wouldn't with the comp 901 spring), just get rid of the rotaters. You can even use the factory 360 springs, just have them tested to make sure they are up to par. You are way over thinking this. I mentioned to you that I used the 48.00 dollar Eddy springs with a .454 lift cam, zero issues.
