Maybe I'll just seal it off with some sheet metal. Like Joe H said, the headers will keep the intake warm. And this engine does NOT have a problem with running warm smile Actually it is the problem... but I've been able to keep it safe from he big bad "red zone" since the thermostat change. Thanks all for your suggestions. I check back so feel free to post more.
