Hi Guys,...

With all this talk about COX 049 engines, its got me thinking about some aftermarket cylinder heads that I once saw. These cylinder heads screwed onto 049 cylinders but were drilled and tapped for normal glow plugs! Therefore one could use regular FOX glow plugs in their .049 engine.

Does anyone know where to get these cylinder heads? Who makes them? Would these cylinder heads decrease the performance of the engine or make them even more finicky?

Sincerely,
Steve T.
