No the heads are still on and they are staying on. The extra spring was the problem for some reason Hughes shipped them with the extra spring and Hughes says it's not supposed to be there. The machine shop just installed them the way they received them. Yes they should have checked them but right now I'm just happy to have the problem solved without having to take this thing back apart. Now I just need to get the camera out of the cylinder and maybe I can drive this piece of crap.
