Buy them from SR20Turbofreak people, we have spoke many times on the subject, I sent him some retainers to look at for testing. He has spent his after hours and weekends checking out all options.
We have spoke over and over again about Spring presure and what is going to be needed for the goals of high reving VE motors,
This will be the best spring retainer combo at the best price.

So, if I were to get these for my VE, I could rev 9000 rpm after running them in? No other stuff needs to be upgraded at the same time?
Sounds cool, and price seems good for what I know. If it goes trough, I'll be on the interested-list till I can get some cash together (wich can be a long time).

Well of course you would want some performance cams guy, if the stock cams drop power at 7300RPM it would be pointless to rev anywhere past that.

Not quite so, if you put springs and retaainers in with stock cams you will gain some more HP from 7300-8000 RPMs becsue the engine would not go into valve float.
There is no need to be reving stock cams to 9000 RPMs though.
Hmm, interested, have they been tested to atleast 8500 rpms?
The man said they are good for 9500-10000 RPMs anf you are asking if they have been tested to 8500 RPMs. I dont get these questions that have been aswered. You my boy but al the info is there.

Agreed, but it would still be pointless you know
If this goes through, I already have my cam plans set.
the 12mm lift issue was with stock valve springs. they coil bind around 12.3mm or so. I have checked 3 sr20ve heads now, bone stock and on all 3 heads there is .520" of retainer to valve seal clearance. that translates to 13.2mm of clearance. I will probobly come out with an updated retainer design that will change that to about 13.6mm of clearance so you could safely run 13.0-13.1mm lift cams.
BEST QUOTE EVER
Thank you for providing proof to the drones that want to believe every word on this forum as gospel about the VE motor. My cam manufacturer said the exact same thing. Actually they said you can get about 14mm of lift before you run into issues if i were to run their retainers.
Thank you for going out of your way to create a product and willing to share with the community
I wish that circumstances were different and I hadn't bought my springs and cams from over seas. I would have bought these from you.
Keep up the good work and I look forward to your advice when I move to Redmond this weekend
