Im planing a budget lq9 build and was curious if ls9 springs will work on a stock 317 head (stock valve & pushrods) with a 222/224 .566 .568 cam? from what I've searched i see that 317 heads are identical to 243s however the valve height is SLIGHTLY taller on the 243. so i guess I=my question will these work on a stock 317head?

Why did you want to change springs?

If your gonna keep the stock cam and not gonna boost you shouldn't need aftermarket springs.

Those springs should fit with no issues. They look like a copy of ls6 springs which are around the same price.

Paid $50 for the blue (used to be yellow from what people say) springs from GM directly. I would just go to a local dealer and pick up a set for that price.

If not ls6 springs should be ok in the mean time.
