Default Which Valve Springs?

Ive got 100k on the car now and was thinking about replacing the valve springs. I was thinking about the 918's. Car will eventually get a mid 230's camshaft, and then later on get heads at which point i will get dual valve springs.

So are those good for stock replacement? Any other recommendations?

i think 918 would be ok for a mid 230 cam with 1.7 rockers, but if i were you i would do the entire head swap at once and save on a 918 spring kit.

Depends on the lift of your cam, stay under .600 and get 918's.
If you wanted just replacement for ytour stock cam, then LS6 springs would be nice and they are cheap.

Im looking at the 233/239, which is just a hair over 600, its 605 i believe.

So basically im trying to find a spring that will handle a 233/239, but also be ok on my stock application until i get the cam

Personally, I would replace with the Z06 kit now, since you are going to replace later anyhow. They are $55 for the kit. The 918's will put a lot more load on your tired timing chain, but that's just my opinion.

This is true, but if your doing a cam swap you should change the timing chain as well. I would put the patriot gold springs in and call it a day. They are the best spring for the money IMO, and they hold a .650 lift. They 918 are only good to .600 and that pushing it.

His initial post indicates he is doing springs and then later a cam, so whatever springs he puts in he is running on his stock cam and timing chain (at least that is what I understood). I agree, once he gets in there and changes the timing chain just go to the duals he plans on using.

I thought about the ZO6 kit, but then when i got a cam i would have to change them again to something that could handle .600 lift a little better. When i do put in the cam i will be upgrading the timing chain and oil pump and all that other good stuff, just cant afford it right now.

Thats why i was trying to feel out if the 918's would be suitable to run while i was stock as well as once a mid 230's cam is installed, until i got heads with dual springs

Any other opinions?

Because the stock springs blow and im over 100k and its time they be replaced. They see the redline every day, and im not sure how long its gonna be til i get a cam, let alone heads. Being in college sucks

So, back to my question about if they will work well in stock application as well as serve me for a while after i get a cam and until i get heads.

If you are running a stock cam and you are a college student short on cash I am sure there are many people on LS1tech with stock low mile springs that would sell them very cheeply..or maybe even give them away free .. you can get yourself a set of PRC dual springs or patriot gold duals that will last a very long time..I have 43,000 miles on a set of PRC dual platinums..they don't cost much either..

in the next month or so I'll have some stock springs with ~65k miles on them available if you want them. Just pay for shipping.

If your stock springs are tired and you are short on cash, the $55 Z06 springs are the deal. They won't be much harder on your timing chain either. Then save your bucks for the final installation of the cam/springs you want. I wouldn't do the 918's on the tired stock LS1 timing chain myself.

LS2 timing chain is $28 ... Z06 springs are $55 for way less than $100 you can solve your problem..even a broke student can swing that deal ...

Well i dont really wanna strip the car down to the timing chain unless im gonna be putting in the cam at the same time.

So it sounds like the 918s would be a bit too much, so i guess im gonna go the ls6 springs, Does anybody have some, where were you finding them for $55??
