Non specific to supertech, my readings have indicated that (and I am by no means a engine builder specialist etc), if you intend on big revs (for example 9k rpm), high lift/wild cams, then it would be a good idea to do retainers. I do understand why you would want to skimp (and as soon as one uses the word skimp, I'm sure someone will chime in after and say, don't skimp on your engine build), as the retainers are 1.5x the price of the springs alone.

Oh and FYI, I have both the supertech springs and retainers in. I guess it just makes you "think" it's bullet proof!

i had indicated that i would close/delete thread as i had started a similar topic and didnt want to litter the forum. i only started this topic as i didnt want the question to get lost in another thread

Blue, thanks for you input but i have decided to go with BC springs and stock retainers.

my friend revved to 9200rpm with stock retainers and BC springs with no issue.

but i am sure the discussion will continue

peace
