How do you choose what valve springs go good with a specific cam. I'm installing a tf stage one cam on gt40s with 1.6 rr's

I am dealing with the same issue, for a drop in replacement, you don't have a whole lot of options. I'd go with the Crane 44308-1 kit. If you want to machine the head, set it up for ls1 valve springs and get some PSI LS1511ML springs for it.Interested in being a VIP member and donating to the site?

Then i'd go with that crane kid for mild applications, ed curtis has a nice PAC spring kit if you wanna get a bit wild.Originally posted by elongoria View Post

Your cam manufacturer should be able to recommend a spring for you, that's what I'd do.Comment

If you want to cut your valve seats, I have some brand new Comp Cams double springs that I'd be willing to let go. I'm not going to use them. They were bought to use with a Wolverine 1087 cam which is pretty similar to the TFS 1 cam.
Other wise, I think the only spring kit still available that'll fit with no machine work is the TFS spring upgrade kit.Comment

Here's what I'm using with GT40 heads, Crane/Cobra 1.7 rockers and Crane 2031 cam on my '92 LX:
Don't use the teflon valve seals that come with the kit though. Just get Fel-Pro valve seals from O'Reillys.
