Default Any idea what valvesprings these are?
I bought these heads used and was told that they are Comp 978's. I sent eh heads back to TEA to have them checked over, and Brent and the guys said they dont remember seeing comp 978's with a blue inner damper spring. Anybody know what these are for sure?

Did they check the pressure to see if they spec'd close to the 978's?

Default At my whits end...what springs are these!!!
I have been looking everywhere to figure out what valvesprings these are. They are a Dual spring with an inner damper spring (hard to see in the pic) so there are 3 springs total. The inner most spring is blue. They are not Crane 832's or Isky 295d's that I can tell. They dont appear to be comp 978's or 987's either. Does anyone know what these could be and the specs on them?

So did they go into detail about its purpose and why they decided to put it there?
