Pac 1218 or PSI 1515 Hello everyone, i will be replacing my valve springs on my LS6 and not sure which i should choose. i did some reading on some other threads but couldnt find anything for stock engines. whats your input on the springs listed below? and if having alot of lift on springs will effect performance or reliability of other valve-train parts.

you definitely dont want the 1515 springs. they're for heads with a different set height.
If you are just replacing springs due to age/use and the originals have been ok for you, then replace them with the same thing. 60% less money too. Sure, you could go to 918 springs but it doesn't sounds like a max rpm situation.
