I recently broke a ls1 valve spring, and need to know the specs for a replacement valve so I can get the car running properly again. I have a 2000, ls1 6 speed car and it's got a stock cam. I'm assuming the years have different cam specs and whatnot, so please inform me of the correct details so I can order the right part! Thanks!

valves are 2.00/1.55 and you do not just change one spring you change them all. Put a set of LS6 or LS2 springs on and you'll be gold.

correct ^^^^,change are the springs.check SDPC or TSP for stock GM springs.how many miles on the motor ?if very high mileage consider new valve seals ,and new rocker arm trunnions bearings.check for push rod straightness .

Ls6 springs from summit are a measly $65...well worth the $$$

Would I need to change anything for those springs to work?

PREDATOR-Z

No, they are direct replacement.

I agree, the stock springs weaken with time/miles anyhow so this is a good time for a replacement. I used the LS6 springs when I rebuilt my stock 241 heads.
