Has anyone done any aluminum casting before???
It seems that with all the type 1 head being cast, someone of these manufacturers might be convinced to run off some new castings for type 4 heads...... Maybe twin plug.... Bigger fins??? Better port design Better flow Lots of things could be done..... Has anyone looked into this before??? Rich |

Unfortunately it's not quite as easy as you would think.
The main problem is the amount of fins, those skinny little fins are very hard to cast. All those fins are absolutely necessary for cooling. I don't know much about casting but I think they are pressure cast. Then it has to be the correct material, right heat treat, etc., etc. Raby's heads will be Type 4 with type 1 exhausts. I bet it will be more than a year before he has prototypes, then he will have to test them. They will have to make 1000's of them to make a profit and they will need some serious coin to bring them to market. Then the price must be within the grasp of the average enthusiast. That’s a lot of hurdles to jump, we'll just have to wait and see what happens. |
