Are you directing any exhaust thru the intake manifold to warm it up, or are the crossover ports blocked? If not, it will take a much longer time for the intake to warm up. That's what heat risers are designed to do.

Is the Torker 2 a single plane intake as I believe it might be? If so, that compounds the problem over a dual plane on a cold manifold.

Without exhaust crossover in a cold climate, likely an intake will not even reach room temperature. I existed for 30 years in our state of Nebraska,,,not Norway but close enough for government work.
