5000 turbo engine valve spring specs?

[Ameer Antar]

Hey everybody. I'm finishing up my engine rebuild, but I'm not sure if I should replace the valve springs or not. The engine shop where I took it has a valve spring tester, but they need to know the stock specs, like spring rate and height for my motor. The motor is from an '85 5000 turbo, so it's a KH type engine. Anyone have this kind of info or maybe a way to find out? Thanks.
