I set them cold with 10 on the intake and 18 on the exhaust. saw them on a thread here. Works good. little clatter but since there solid i'll deal with it. Much much quieter than before.
Much better. If you set them loose/cold they tighten up when the engine warms up. The exhaust of course gets hotter and expands more. That's why the exhaust spec is looser than the intake. I always set mine cold and usually a thou or two looser than spec.
