Can somebody lead me to the correct valve springs for running a ZZ4 camshaft in my L98? Any help would be appreciated.

 

Factory ZZ4/LT4 springs
Get the lightweight LT4 retainers while you are at it

Doesn't the ZZ4 cam make .510 lift? I plan to use 1.6 ratio roller rockers, so wouldn't these springs be out of their operating range? It says they are only good up to .525 lift.

 

Well,you didn't mention that in your post did you?

Look up a 1.32 Od spring that is good for the lift you want to run

 

I can't seem to find any in that size.

 

You're probably going to need more than just the right springs to work with the .544 exhaust lift 1.6 rockers are going to give you on the exhaust. Like having the guides cut down for more clearance.

Comp cams has an extensive line of valve springs both standard and beehive style. You might want to call and ask for their recommendation.

 

Yes, I've been thinking about this too. I'm gonna call them Monday and if nothing else I might just go with the 1.5 ratio rockers and be happy.
