[Fot] TR6 cylinderheads

Are you running a restrictor in the T-stat housing?  I ended up with one with a hole about the size of a dime.  Made a huge difference.  Also the highest pressure cap you can find

I've some problems with a TR6 race engine : the engine is pinking and overheating. Compression ratio is 12.5. Comparing the cylinderhead of this engine with another 6 cylinder head (probably also from a TR6 , but from a  Triumph saloon is also possible) : it turns out that my cylinderhead is lacking 5 coolant passages. My cylinderhead has only a passage just beneath outlet port no 6. The other cylinderhead has passages beneath every outlet port. I didn't know of this difference  between 6 cylinder heads. Does anyone know which cars do have which cylinderheads? Can I add these passages on my cylinderhead, hoping for better cooling? I've been working on this engine now and then since 2 years. It belongs to a racecar a friend of mine has built. He has lost interest in this racing project and I bought the car. I'd like to see it on a racetrack some day.
