Need new valve springs

[projectPONY]

I'm getting my Edelbrock Performers worked on, and the machine shop called me today and said my springs were too light for the X cam that I'm using. Can you guys recommend a good set? I have no idea what to look for.

TIA

You might as well have typed that in Swahili.

They are ls1 springs, 130 seat, 370 open, extremely good wire, what installed height on those heads?

I have no idea on the installed height either. How do I find out?

Call machine shop and ask for installed height, they will have a tool to check it.

Here is some interesting history on PSI, they changed the game.

A plaque underneath reads "Jeff Gordon, 1998 Rockingham Win." This tube of steel wire was the first PSI valve spring used in a Nascar race. It revolutionized engine building and the country's most popular motorsport, but few people have ever heard of it.
