No he meant a heat gun to preheat the engine to make it easier to start.
Jet, I don't mean to argue,but if you read his posts I believe he really means temp gun. He's talking about the "Heat-Cycle" break-in where you need to get the engine up to a certain temp, hence the need for a temp gun. He says in one of his post "The heat cycle is pretty noob proof. If you've got a heat gun then you can do it with no problems".
But in another post "Heating the head before you start will just make startin the engine easier, its not a necessity." Therefore, a heat gun would not be needed.
So,how about it VB, which did you really mean???? :\
