RE: Cooling Head
i jsut got my warhead, it was used so the fins on the head were bent,and that's why i'm trying to look for a replacement.

RE: Cooling Head
250 is a good safe number. I usually for any engine try to keep it under 270. I havent had a temp gun lately though so I just use the spit test. Spit just a little bit on the glow plug and if it aggressively sizzles under 3 second then I say it to hot. I also go by smell, feel the head for a second, blah blah blah.

RE: Cooling Head
My suggestion to you would be to just get a stock head then. Unless you are looking for a change in how the engine looks, the stock cooloing head will work fine. Lots of people think that the way to fix an overheating problem is to change heads but all that does is to mask an underlying problem. In other words ot treats a symptom, not a problem. You can probably find a stock head on e-bay for not a lot of money.
As for temps, I agree that taking the engines temp all the time is kind of pointless. Tuning for performance rather than trying to hit a certain temp is a far better way to tune.
If you're just courious then your engine needs to always be run above 200 degrees and never over 300 degrees with the best operating range between about 220 - 270 degrees. Keep in mind that every engine is different and operating temps will differ on the same engine depending on ambiant temps, tuning, humidity, how hard the engine is working, weather there are cooling holes in the body, etc, etc, etc.
