Plugs fouling quickly

I have a 70 911 with a stock 2.2 and an MSD Street Fire. I recently had it serviced by a reputable Porsche mechanic and the engine is in good health. My problem is spark plugs fouling on every trip out, I don't do short trips, mixture could be a bit rich but not enough to cause fouling every trip. Has anyone used hotter plugs or iridium plugs with a similar set up? I didn't check what plug or heat range I have in before writing this which doesn't help but some suggestions would be helpful. Thanks
