Default Dynamite Head Vs. O'donnell Head

Hi everyone,
I have an O.S. 15 CV-X with a stock head. People say i should get a new head because it is running really crappy (ie: stalling). I have adjusted the carb and i still have the problem. Also I've heard the engine will be more tunable with the new head. My local hobby shop in Reno carries a dynamite head for $40.00. I just visited nitrohouse.com and looked at the blowout specials. They have an O'Donnell head for an amazing $15.95! I'm torn between which head will give me greater performance and cooling. Any suggestions or reviews on these two heads will be greatly appreciated.

Yep, the stock CV head isn't the greatest cooling head. I would go with the O'Donnel head, and its even better if you can get it at that price. It should drop your temps considerably, approx 30-40 degrees.

Changing the head also isn't really going to make the engine more "tuneable". If it is stalling right now it just may be majorly out of tune, or if it is stalling out after running for a few minutes it may simply be too lean and is heating up too much. Although the new head will bring temps down you should also richen it up a bit to get a little bit more lubrication/fuel through the engine.
