To clarify just a bit, the 907 will NOT overheat if the engine is within spec and has a radiator capacity appropriate to the area it is being driven in. The minor problem on the 907 engines, as I understand, is that they tend to get "hot spots" toward the rear of the cylinder head instead of keeping a more even temp throughout. Does that mean every owner should run out and try to fix this problem? I think not. For most people it's a non-issue. Most owners will never know this condition exists in normal service. Small improvements will certainly help a performance engine, but if you want to bypass all the early head issues completely and have a goodly sized budget, going with the vastly improved Lotus Zeus cylinder head would be the way to go. Garry Kemp often has one available.
