I think they actually use glow plugs from a deisel engine in the tailpipes for that. I'm not sure cause I've never done it. You probably need to run a very rich mixture or have a cam with lots of overlap. The overlap would allow some unburnt air and fuel to pass right through the chamber to the exhaust at low rpm's.
