Default Re: New block

I like the idea of keeping the valve/lifter area stock. Some modes to the water jacket in this area will help those that want to search for more power happy. As for the center exhaust port, it's the best flowing port in the engine. Just use a flow bench. The fact that it is used for two cylinders has no affect on flow, as the cylinders don't fire at the same time. In fact, The firing order of the Flatheads fireing order is such that all the end cylinders fire in succession first. Then the center 4 cylinders fire in sequence one side at a time. Now with the proper exhaust manifold you can use this to evacuate the end cylinders. Plus you don't need to make any mods to the block. So leave the center exhaust port alone. Pretty soon we'll get nothing.
