Hey, new to the forums. Been looking around and haven’t found much info on this combination but I was curious if it would be a smart idea to put the stage 1 cam in with custom gt40 heads. The guy I’m purchasing them from says the heads have a max valve lift of .475 and I believe the stage 1 is .499. I’m not sure if this is an issue or not. Sounds like it could be and just wanted to see if it is. I do plan on getting new springs for it if this is a viable combo.

Springs that match the cam are a must. If you numbers are correct, coil bind and bending things are going to be upsetting.

Talk to the cam manufacturer about recommended spring rates, then talk to a machine shop about swapping the springs, or you could swap them yourself.
Without knowing what other mods you have I don't know if the cam is even right for your car

If the cam is not a bad match, springs are not a big deal to change. TFS should be able to help.
