If you plan on keeping the internals stock...
Go with stock valvesprings.
Why do you think you need to replace them? One break?

it sounds like the #7 cylinder is knocking a valve spring. my brother in law who owned it before me recommended going with a stiffer spring saying the stock wasn't stiff enough. i plan on upgrading parts to fix it up too. we did a compression test and the cylinder matched all the other cylinders so i was thinking of going with the springs.
