So i got a 89 vert recently and im looking to slap a b303 in it because my friend has one laying around. Im on a tight budget and i was wondering if anyone just happened to know the diameter of the stock valve springs? I just was curious because id rather just buy a set of springs instead of the whole TFS kit. If anyone knows it would be greatly appreciated.

You don't need to change out the valve springs to run a B303 cam as it's only .480" lift. You do have to do a lot work to change it out and it's really not going to give you much of HP boost without updating the heads and intake. If you could find a set of GT40 heads and Explorer intake that you could install while you are at it, you could pick up some decent gains and people almost give that stuff away.
