need valve springs help I wanna run a cam that has 670 lift. I wanna run the new l92 heads which have the 2.16 intake valves in them. Does anyone know what valve spring I can run with this cam?
Why do you need .670" lift with a 2.160" valve? You don't need as much raw lift with more valve size.
Two other things, the valve length will probably need to be increased to get something that can handle that lift in there since the coil bind would have to be extremely low to get it there.
You need to have these heads in your hands and measure everything to figure all of this stuff out.

Yeah, I understand they still flow well over .600" of lift. The problem being how to get valves that are long enough AND most applications will not need more than .600" lift....
Sounds like you are just trying to do everything cheaply, which on new untested stuff is not going to work out well. A LS cam is just not going to work well with a L92 because it's probably way off the normal.

Longer custom valves, buying and trying multiple springs that "should" do the job (but you will not know till it runs), the area of the spring seat locator and maximum diameter you can put in there.... etc... it's not just a bolt together deal. Top that off with a cam that's not going to perform well with it and I just don't get it.
