I am with Fog, hood and windshield will drastically decrease air flow over the radiator. I took my windshield off my 2 seate. My main issue was the smell of exhaust, smell of gas, engine blow by fumes and I would get a huge wave of hot air that would hit the back of my neck and head from the radiator. Basically the air was swirling or moving forward in the cab. It got old quick. Easy solution was ditch the windshield.
Not saying you are guaranteed issues but be prepared with some solutions if you do.
