Thanks for all the info, i should have said from the start that it is for a 1/8th pan car.

GT and offroad motors seem to be plenty available at shops like KleinKram, but for pan cars i see nothing specific.
All of them except for two 2.11cc motors come with big heads, 5 or less ports, U shaped exhaust flanges, and carbs the other way arround.

I feel like i am overthinking this, but for how expensive these motors are i really want to get the correct variant.

Something like this seems to be what i should be looking for?
