If your stated temps readings are correct and your timing is at least 32 and your primary jetting is in the ball park then low cranking compression will tell you that your cam is in retarded which would be my guess at your issue with coolant temps!

Speaking of timing... In an earlier thread I mentioned having an overheating issue when my vacuum advance was connected to a "partial" ported vacuum, which was not giving me enough advance at cruise speed. Make sure your advance is connected to a port that is providing full vacuum at cruise. Just something else to consider.
