i didn't want to risk the new springs, i sold the set i had. just use patriot golds and you won't have to worry about dropped valves, their only $100 more. any high performance spring should be up to temp before you start cranking on them. stock springs are a lot more forgiving than aftermarket.

 

I'd just go better and get duel springs IMO. I had the old 918's and one of em broke within 17k miles on a low lift cam. Think i'll be running patriot from now on.

 

I found this thread, post #29 and #32

Here are he pics,

 

Its not worth the risk, believe me!

Run the Patriots and dont look back. I guarantee that if you break the 918's its going to cost you more than 100.00 in the end.

 

For sure! Cutting corners is great if you have nothing but good luck.

 

what is considered putting them in wrong?

 

The more I read about these problems the more I think that the yellow Z06 springs are best for all .600 and below apps. They never break and are only 12lbs lighter open pressure than the 918's. I guess I should have kept mine.
