I am using the patriot springs and have a G5X2 cam. No problems after about 1k miles.

Agreed. Those duals or comp 918's. Comp 921's would be better, but they are a little expensive.

For one, 918's are currently rated to .600 lift, though the G5X3 probably goes a little over that it's not gonig to be by much. They are a very good spring with excellent dynamics due to the beehive design. Not only that, but they used to be rated at ~.625, before the 921's came on.

True, but TEA uses the same spring as PRC, manufactured by associated, but for a few bucks cheaper still.

And for how long did you have them in there??
Was you preload on lifters right??
What rockers were you using??
Did you ever over-rev on a downshift with those on? ever?

That is a pretty bold statement with no other info. Give the full picture please.
