valve spring color?
Hi, I just bought a set of brand new 243 heads and the springs that came with the heads are blue striped. Can anyone tell me if these are ls6 springs? And also what the lift are?

i would call whoever you bought them from and if they dont know or sound like they are even a little unsure i would buy new springs. nothing like breaking a spring and having a piston slam into a valve

Hmmm
Perhaps a couple of pics of top side and underside?
If they have orangish/redish valve base then they are LS2.

Nope... those came from an LS2 243 head. Non-sodium valves, etc...
Those came on complete NIB LS2 heads I've received before. They may be the same spec as '01 LS6 springs though. I don't know. I've got them laying around somewhere (the springs new) I guess I could check them real quick.

Never heard of a 931. I know they make the 921 (dual), 913, and 930 springs.
I am going to have a buddy see about checking the spring rate of these springs and compare it with the early LS6 specs and 918 specs. We should be able to find an answer this way.
