Couldn't find the video about using type 3 cooling tin. I did watch his 15 minute video about camshafts (it was one of his shorter videos) and from what I saw I wouldn't trust or believe anything he said. There wasn't 1 bit of solid information in the whole video. All I see is a guy posting videos to get enough subscribers to make money off of Youtube.

I'm guessing that at parade speeds the engine is re-ingesting a lot of spent cooling air. The air is coming down through the cylinders, hitting the ground and hanging out around the engine where it just gets sucked back in to the fan and carbs again (and again and...). The air needs to be directed around the lower parts of the cylinders/heads to cool them properly and then directed out the back so at least the bulk of it doesn't end up back in the engine compartment. I would try modifying sled tins to attach to the 911 shroud. A remote thermometer in the engine compartment will tell you how high above the temperature outside the car and if your efforts are doing any good. 

If the parade thing is really important, maybe a fan of some sort on the firewall bringing in fresh air from forward of the engine compartment? I believe there are 12 volt bilge pump fans that are fairly compact and move a lot of air.

Hope this helps. Al
