I don't think 210 is anything to get too anxious about but I second checking your timing. I suspect you may not be running a vacuum advance unit as that seems to be pretty common with a lot of Cobra motors. If not, then initial timing could be very critical to your engine keeping it's cool. If not running vacuum advance the distributor needs to have the centrifugal advance limited so somewhere around 15 to 18 degrees initial timing can be run.

If you are running vacuum advance it should be hooked up to manifold vacuum and not a ported vacuum outlet. My 66 Corvette was set up by GM for ported vacuum advance but by just switching it to manifold vacuum I dropped the engine operating temperature significantly.
