I believe the head design of all multi valve engines are very poor, they only work because of the multi valve configuration, the ports are all too low for a decent angle to the back of the valve head. The manufactures used the multi valve to make the engines shorter in length. I would like to see a 4 valve with the ports up high, even higher than the best chevy small block head. Remember "Smokey" you want to flow around the whole valve not just one side.
Not to knock 4 valves they do work but still not the best possible. Look at the Pro Stocks of today!
If only I had a block of aluminum.
